FN 57 Magazines dissected ***added more pictures***
Here is my way of saying thanks to every one on this forum. I might not post A lot but i do read a lot. i hope this can help
Left to Right: Promag 30rnd, Promag 20rnd, FN 20rnd, FN 10rnd
Top To bottom: FN 10rnd, FN 20rnd, Promag 20 RND, Promag 30rnd, CMMG 30rnd EXtenshon
Left to Right: FN 10rnd, FN 20rnd, Promag 20rnd, Promag 30rnd
Left to Right: Promag 30rnd, (extension removed) Promag 20rnd, fn 20rnd fn 10rnd.
Top to bottom: FN 10rnd, FN 20rnd, Promag 20rnd, Promag 30 rnd, CMMG 30 rnd spring
Left to Right: FN 10rnd, FN 20rnd, Promag 20rnd, Promag 30rnd
Left to Right: FN 10rnd, FN 20rnd, Promag 20rnd, Promag 30rnd
Left: Promag Extension Right: CMMG Extension
Left: Promag Extension Right: CMMG Extension
The Factory magazines are Clean and there are little to no Plastic Flash... They have markings that indicate FN or 5.7x28... there is no little to no drag when removing or installing the followers. The 10 rounder have a Gray Followers but are identical and will swap to all the bodies.
Promags: the 20rnd spring is to short... the 30rnd is about the same length as the cmmg. There body and there flowwers have lots of plastic flash that causes problems. there followers drag on the body, but if you install the FN follower it does NOT. all the parts weather FN or Promag are interchangeable. Promags have there logo on the base plate and there are pins visible on the body near the lips....
For the Price of Promags. 20rnd $25 30rnd $35 you get what you pay for. but with a little work of cleaning the flash and the followers and a new spring (Elite Spring??dunno i don't own one), you might be able to make a Reliable Magazine..
I Have more pictures but i think the once i posted should do the job.
-Mekunic
Here are a few more pictures that i think everyone can benefit from...
Left to Right : Promag 30rnd, Promag 20rnd, FN 20rnd, FN 10rnd.. Note that the Promags have a "dash metal pin" while the FN 20rnd has a "round pin"... FN 10rnd has no pin...
Left to Right : FN 10rnd , FN 20rnd, Promag 20rnd, Promag 30rnd. Note that the rough sanding marks are more pronounced on the Promags while the Fn has very fine marks..
Since 20rnds is the standard ill give you a more pictures between the two....
Sorry i added so much pictures, but i wanted to give all of you as much detail so you can make the decision to buy FN or Promag... On my testing with the 20rnders, once i clean up all the plastic flash and used the FN spring in the Promag body it worked as good as my Factory... The ProMag spring is too short and weak... i can put in 21rnds in the ProMag magazine, but once i installed the FN spring it only held 20rnds...

Sticky'd.
Re: FN 57 Magazines dissected
Thanks everyone......
I'm gonna make a few additions later this week... I may possibly have a Promag with no markings being sold as Original... I can't check now cause i left the Mag in friends car

Re: FN 57 Magazines dissected
I like the look of the promag 30 rounder. Is the extension sold separately?
Re: FN 57 Magazines dissected
not that I have seen goants, but I haven't seen everything. Surprising, I know!
Re: FN 57 Magazines dissected
Nope... i talked to a few vendors at the gun show and all said ProMag is only selling them as complete magazines..gotants wrote:I like the look of the promag 30 rounder. Is the extension sold separately?
But all the 20rnd/30rnd Magazines parts weather its Original/Promag/CMMG are interchangeable...You take them apart like you would a normal 20rnd magazine. The extension just needs a bit more squeeze to release the base plate.

Re: FN 57 Magazines dissected ***added more pictures***
Has anyone used the Promag 20 with the Elite spring made for the FN5.7? If so what are your thoughts? I'de love to buy a couple of FN 20ies, cause I have Elite springs waiting for them.
And thanks again Mekunic

Re: FN 57 Magazines dissected ***added more pictures***
Hmmmm.... If one were to say... Buy ten CMMG extensions... Could one theoretically make a huge magazine that holds something like 100 rounds by training all of the extensions together, or do the extensions have a built in baseplate that would prevent this? (Of course you would need a huge spring to do this...)

Re: FN 57 Magazines dissected ***added more pictures***
CMMG intended to make the magazine extensions stackable - unfortunately what they produced doesn't actually stack. Personally - 30 is nice, but I'd rather have two 20s than a 40.Augustus wrote:Hmmmm.... If one were to say... Buy ten CMMG extensions...

Re: FN 57 Magazines dissected ***added more pictures***
Wow, I likey this post!
Agree w/ 30 being more than enough for extended use. I see no practical purpose stacking to 100 rnds other than to have a walking stick for a gun.

Re: FN 57 Magazines dissected ***added more pictures***
I need to take a pick, but the recent batch of FN factory mags no longer have that small piece of metal in the mag body.
Here we go. Also the FN verbiage is no longer present. Also the number of small hole like indents have changed.
Side note the basis on these are a MF to remove. I installed EA extra power springs in all of the and I had to use channel lock pliers to compress the mag body enough to get the bases off.

Re: FN 57 Magazines dissected ***added more pictures***
For different weapons I've had bad results with ProMags, maybe they're better with the 5-7. At first I saw the ProMag extension and I was like "thats cool it matches", but after looking at it on the gun, it looks beyond stupid. I like the look of a mag extender, not the look of a gun thats WAYYY out of proportion.
Re: FN 57 Magazines dissected ***added more pictures***
I agree, but I hate to reload. I have a 6 pocket mag pouch that I keep 4 of the 30's in and 2 of the 20's with one 30 in the weapon. When I go to the range I blow off 180 rounds and the ProMags work as well as the 3 factory mags, I don't see and flashing or burrs at all. It looks like they are made to the same specs. Now if I can find them in Desert Earth, I would buy at least one!SeaHawkDriver-B wrote:For different weapons I've had bad results with ProMags, maybe they're better with the 5-7.

Re: FN 57 Magazines dissected ***added more pictures***
What's the tolerance on the stock FN mag springs to stay compressed for long periods of time? If I were to load one to capacity and let it sit for an extended period of time (years) would it hold up and still perform?
I ask because when the P-Mags came out from Magpul, there was a lot of hype around the advantage of being able to load 'em up, cap 'em, and let 'em sit until retirement age (or the zombie apocalypse....whatever.) It's not really a *need*, more a curiosity.
Thanks!

It would be the same as the PMAG springs. As most springs. The repeated compressions matter more in wearing a spring down than the one time held compression.
That said, over time, compression of both PMAG springs and FsN and any mag springs will distort it.
Hope that helps.

I've been after some of those "made in Belgium" mags for about a year now, any ideas on where to find 1-3 new ones?
Re: FN 57 Magazines dissected ***added more pictures***
had all jams and not feeding problems with the factory Pro-Mag 30 after only 30 days, 30 rounds in it!!
maybe i need another spring in it or just throw it in the trash!!!

Re: FN 57 Magazines dissected ***added more pictures***
From what i've read the only way you'll get the Promag to work is to use the FN mag body and follower, and the extended spring from the CMMG kit.
I took a 30rd CMMG apart today, and loaded it up to see how many rounds fit in the FN mag body before the follower extends down into CMMG extension, where there is the potential for the follower hanging up on the mag seams.
It's 27rds.
As long as you only load 27rds in the magazine, there is no possibility of the follower hanging up on the seams at all because the top of it never gets into the CMMG extension at all.

Re: FN 57 Magazines dissected ***added more pictures***
VERY interesting. I will try this. Mine is smoothed down with fine-grit sandpaper, but will misfeed the 2nd or 3rd round and is not reliable for the first few. I think I'll try to get an EA extra-powered sling and see if it works. I only use the 30 rounder for competition so it's not a critical issue, as I'll just pick up 1.5-2 seconds on a reload.Valorius wrote:From what i've read the only way you'll get the Promag to work is to use the FN mag body and follower, and the extended spring from the CMMG kit.

Re: FN 57 Magazines dissected ***added more pictures***
I was hand cycling the weapon today over and over from 27rds to 20, and it appears to work perfectly (as logic dictates it should since the follower lip never reaches the problem seam area). I'll be going to the range within the next week and will test it extensively to make sure it's 100% reliable, but i am fully expecting it to work.

The CMMG extensions do not have built in baseplates, they use the one that comes with the FN mag. They do come with a replacement spring but as far as chaining them together to make 100rnd mags, no one has a spring that big and who wants a mag that when the gun is at eye level reaches down to your chest?Augustus wrote:Hmmmm....

Honestly, I wouldn't be shocked, AC. People have done dumber things that they deem cool or, in their minds, applicable to some fantasy scenario in which they get attacked by a mob of monsters. In fact, there are many of the examples on this forum, sadly. Although not as frequent in percentage as other forums, it is still sad.acmeraptor wrote:The CMMG extensions do not have built in baseplates, they use the one that comes with the FN mag.

Yeah, with no qualms. I mean, he probably fantasizes about zombies all the time and he has all the gear to protect him (skill?) in event of "SHTF" or "ZOMBIE APOCALYPSE", so I'd be doing him a favor by making his dreams come true, right?PainKillaX wrote:You'd serve him to the zombies on a plate?blueorison wrote:

Anyway, we should merge this thread with the other CMMG thread, and get back on topic.
We will be testing out a CMMG extension in two weeks.

Re: FN 57 Magazines dissected ***added more pictures***
Got 2 Promag 30 round magazines this week and they worked well, but did not slide in and out or seat as easily as the FN mags. Purchased 2 sets of metal lip protectors from Elite Ammunition, but they have not yet arrived. The pictures of the various mags were awesome.

Re: FN 57 Magazines dissected ***added more pictures***
I just bought a new FIVESEVEN (can't deal with the capitalization thing), and noticed that my mags do not have the metal inserts, at least no metal is visible inside the magazine at the top. (I also noticed the earlier post that FN appears to be making them like this now.)
My question is if people have noticed any adverse consequences from this change, either with regard to the durability of the mags or reliability of feeding. As I recall, Glock tried using all-plastic magazines at first, then went to metal inserts. Surely there must have been a reason for this.
Also, I'm searching for a reason why there were 3 failures to feed on my new FN in the hundred rounds I put through it today (yes, blue-tipped factory ammo). The rounds wedged at an angle, point hung up on the chamber rim.

In correct. FNH has not changed how they make their mags recently and the steel is molded into the top lips of the magazine.Mithridates wrote:I just bought a new FIVESEVEN (can't deal with the capitalization thing), and noticed that my mags do not have the metal inserts, at least no metal is visible inside the magazine at the top.

New gun or crappy SS197 ammo.

Re: FN 57 Magazines dissected ***added more pictures***
I stand...er sit corrected. I took a closer look, and there is indeed some sheet metal molded into the magazine near the lips. The reason I didn't notice the metal is that it is matte black. In the pictures posted at the top of this thread, it looks like bare, silvery sheet metal. I'll see if I can figure out how to post pics to this forum.panzermk2 wrote: In correct.

It is indeed a brand new (not previously owned) gun. New factory SS197SR FN ammo, fresh out of the box. When you say "crappy SS197 ammo" do you mean that I may have gotten hold of a bad batch, or that SS197 ammo is all crap? (That would be bad news, as I just ordered 1K rounds of it...)panzermk2 wrote: New gun or crappy SS197 ammo.
By the way, I picked up the notion that FN had eliminated the metal from the magazines from an old post of yours (which I perhaps misunderstood), dated Sun Nov 01, 2009 1:58 pm:
Thanks for your reply!panzermk2 wrote: I need to take a pick, but the recent batch of FN factory mags no longer have that small piece of metal in the mag body.
Here we go. Also the FN verbiage is no longer present. Also the number of small hole like indents have changed.

Re: FN 57 Magazines dissected ***added more pictures***
I was referring to the spar of exposed metal at the back of the mag. This spar like a plastic model spar, holds the metal insert in place in the mold as the liquid polymer is injected into the mold.

The "how to" for that is in my sig line.Mithridates wrote:I'll see if I can figure out how to post pics to this forum.
The 197 is anemic & made weak by FNH to appease the brady bunch peeps. EA's ammo makes better use of the capabilities of this round.Mithridates wrote:When you say "crappy SS197 ammo" do you mean that I may have gotten hold of a bad batch, or that SS197 ammo is all crap?

However, you shouldn't have any problems with using 197 once your FsN is broken in. I occasionally feed my FsN EA ammo & then but I primarily use 197s without any problems. I have even put EA's heavy duty recoil spring in mine & still have no problem with 197s.

Re: FN 57 Magazines dissected ***added more pictures***
I've tested the hell out of the technique of just using 27rds in the mag.Valorius wrote:I was hand cycling the weapon today over and over from 27rds to 20, and it appears to work perfectly (as logic dictates it should since the follower lip never reaches the problem seam area). I'll be going to the range within the next week and will test it extensively to make sure it's 100% reliable, but i am fully expecting it to work.
Elite sells an extra strength spring for the extended 30rd magazines?
I actually load them to 27+1 in the gun, and 28 in all the spares. As long as the 28th round is chambered manually when you insert a fresh magazine it works perfectly.
I also tried loading them all to 30, even after shaving the seams, and i still had stoppages when they were fully loaded, so i will definitely be sticking with the downloading strategy.
I have 13x 30rd magazines, so i have a pretty good body of samples to work with and form a sound opinion on IMO.
Figured people might be interested in my results.

NEW MAGAZINE DESIGN AS OF LATE APRIL 2012.
FN has added a full length vertical rib inside the front of the magazine.

Re: FN 57 Magazines dissected ***added more pictures***
Just a headsup, I have the new mag type Airdog pictures above, as well as the CMMG extensions. So first I want to say the extensions seem nice, with good springs. I only just got them in this morning, and only using one full mag, now 30 rounds in each of my 3 magazines, they fed fairly well; AFTER some grinding down of the new rib Airdog makes note of in his post. Just grinding at the baseplate end so the spring has a ramp to hit the rib seemed to do the trick, although the rib does make the included spring have a tighter than intended fit up the rest of the new mag type. I had one mag feed perfectly fine, one had one doublefeed, the other two(this after grinding). I guess its possible to grind or cut down the entire rib, but hopefully I'll get them working with out doing so. This is really only a fun gun for me though, so I cant say I'm terribly concerned over the performance.

Re: FN 57 Magazines dissected ***added more pictures***
Since I travel, I wanted to have a couple of 10 round magazines be be compliant in certain states. So I bought a couple from a midwestern retailer. I thought they'd be made by FN, turned out to be Pro Mag (PM). My gun is new & the 3 original FN mag's that came with it are like the ones shown slightly before my post with the internal separator for the cartridge tips. The PM do not have this separator but the big problem, I have not live fired the PM's yet and see no reason to at this point, is inserting the mag into the gun. As soon as the mag contacts the mag release in the grip of the gun's magazine well, further insertion becomes increasingly difficult up to the point of locking into battery.
Then when you depress the mag release, the PM mag barely detaches, pops loose, from the gun and you must forcibly extract it from the magazine well of the gun.
I have e-mailed and phoned Pro Mag (twice) trying to speak with Tyler their mold engineer about what I see as the problem With these mag's. Both have a date code of 08-08. I don't know if this code is the manufacture date of the mag or the latest revision date of the mold.
I have contacted the retailer and asked them to hold back on selling these and their response seems to indicate they will. I prefer to work with Pro Mag to help them solve this problem but seeing I'm getting no response, I guess I'll have to send them back to the retailer as defective.
In review of the PM mag, the problem is the exterior width from the mag lock notches to the top where the cartridges are loaded into it. The angled surfaces in the aforementioned area are too wide and rub on the inside of the magazine well. The rest of the mag width towards the case portion of the cartridges seems fine.
It seems one person shortly before my post is experiencing the same problem as I am. The 10 and 20 round mags seem to use the same exterior housing, so the problem exists in both mag's.
Anyone else seen this issue with their PM mag's ??

Re: FN 57 Magazines dissected ***added more pictures***
well, that's interesting. The Mk2 I just got a few days ago...the magazine in the pistol had the new magazine with the vertical rib, but the two extras - no rib. Hope that isn't important, and also a bit weird that the Mk2 is new, the design change was over a year ago, and I'd still get old style mags?

Re: FN 57 Magazines dissected ***added more pictures***
It's no biggie as long as they work, they are supposed to work in both models.
As with all production changes, some of the old style will be around for a while and remain in circulation. If I had to guess, they probably had the (old) spare mags in the case already, awaiting the switch over to the MkII. Then, once the new gun rolled out, they put in a new mag (probably also fresh from the production line), dropped it into the case, & shipped it out.
It's only a big deal if you're one of the OCD types who HAVE to have the same mags :laugh: Even then, you can probably just trade with someone to get all the same type.

Re: FN 57 Magazines dissected ***added more pictures***
Hello
I am new to the forum but not FN products. I just picked up a new five-seven MKll. It goes nicely with my PS90 and FS2000.
My thoughts are about the mags. In the box I received one second gen mag with the ridge on the front lip running down the inside length of the mag. The ridge runs between the bullets. The other two mags do not have the ridge and are first gen mags. I called FN and a tech stated they are the same but for the ridge and work the same. The ridge was there to simplify production. He also stated they have a stockpile of the older style and just pick up mags to put in the pistol boxes. Dosen't make any diff in performance.
Anyone have any knowledge as to if one is more reliable than the other.
I know on mine the newer ridged one is more difficult to load with shells.
Thanks.

Re: FN 57 Magazines dissected ***added more pictures***
Bullsh!t the mag lips break off on the old style. That is why the rib is there and why I make and sell lip protectors for the old style mags.
"simplify production" What utter BS. A whole new set of injection molds? New Body? New followers? New springs? ALL had to be redesigned. Too add rib INSIDE to "simplify production"

Thanks for the info. I knew it was crap. But how does the ridge in the front prevent breakage of the lips in back?

It is only the front lip that breaks. The main curved ones are steel reinforced. As you can see in this pic it's the front lip that the rounds are dragged across as they chamber is the breaking point. This mag's lips had broken and I installed our protector.

Re: FN 57 Magazines dissected ***added more pictures***
Hi All:
I read this forum just about every other day, but don't post a lot. I saw an ad from CDNN about a month ago for the extensions from CMMG to make the mags 30 rounds for $9.95 and $4.95 shipping. I could not resist and bought 2 at this price. As I live in the desert about 45 miles away from Las Vegas it was a while before I could test them because of the wind here. Took them out last week and they performed flawlessly. Would recommend the for purchase.

Actually Jay they do warranty them if they break. This last year I had 2 break that I had not had the time to modify them with your kit yet. I called FNH and they had me mail them the mags. They sent me 2 of the new versions as replacements. It took about 3 weeks from start to finish.panzermk2 wrote:FNGuy wrote:Is FN warranty'g the old style mags if the lip breaks off?panzermk2 wrote:Bullsh!t the mag lips break off on the old style.

I have about 20 sitting around with cracked feed lips I have not bothered to fix or throw out.

truth be told, I've not browsed the entire thread, but I'd like to add a little information that I just encountered:
yesterday, I picked up a MKII & the magazines that were included with it (20's) did NOT have the metal pin in them: I'm assuming this is one of the features of the so-called "new" style magazines?

Great pictures of the comparison.
I wonder if anyone has ever attempted to make an after market mag follower?
I was looking at a orange 5th gen Glock mag the other day and got wondering that. I seen the gray one in the start of the thread but don't recall ever seeing any others.
