First Outing With My Five Seven MKII
Posted: 05 Sep 2017, 18:20
I was finally able to get to the range today and took my Five Seven with the Jarvis barrel and Dead Air Mask suppressor. Ammo was SS197, SS198, AE, EA QuieTOR 5.5 for pistol
I fired:
20 rounds of SS198 with no issues
5 rounds of EA QuieTOR 5.5 with suppressor with no issues other than a lot of blowback hitting me in the face (I had too much lube on it I am pretty sure)
5 rounds of EA QuieTOR5.5 - round 1 fired; round 2 did not fire and when I ejected it, it had a very slight primer hit. Round 3 fired. Rounds 4 & 5 did not fire, no primer hit.
OK, so I thought I'd try the SS197 ammo and some more SS198 and absolutely nothing would fire. I could definitely feel the striker firing (firing pin coming forward) but there were no primer hits. I wasn't at a range where I could just tear down the gun so I packed up and went home since this was the last gun I was going to shoot anyway.
What I discovered:
brass was jammed in the firing pin channel at the very front....so the firing pin was coming forward and hitting the jammed in brass instead of the bullet. I guess the debris got in the firing pin hole and clogged a little (hence round 2 above that did not fire but had a slight primer hit) and then more clogged and jammed in to totally seal off the hole and from that point on NOTHING would fire (because the firing pin couldn't pierce through the jammed in brass).
Remedy:
I took off part of the adjustable sight and then the slide cover roll pin and removed the slide cover. I then removed the firing pin and checked it out and it seemed OK (time will tell). I tried to pry the jammed brass out from the front of the channel but couldn't so I ended up getting a very slender piece of metal and punching out the jam from the rear of the firing pin channel forward. Cleaned, lubed and put the slide all back together (my first time doing that and it went well....no missing parts, no extra parts and no mars/damage....a first for me ..... ).
So...............back to the range next Tuesday. This time I'll fire 20 round SS198, 20 rounds SS197 and 20 rounds AE ammo without the suppressor but using the Jarvis barrel. I'll make sure the slide is clear of debris, etc and then I'll add my suppressor and shoot 20 rounds of the Elite Ammunition Quietor ammo and see what happens. The jamming started once I first used the QuieTOR but I'm not sure if it would be the ammo or the suppressor or the blowback or what (and to be fair, I did shoot 20 rounds of SS198 prior to the QuieTOR). I just looked at my suppressor and it appears fine, no damage to it.
I'll post a follow up range report next week. With that said, the 20 rounds of SS198 shot like a DREAM as did the first few subsonic rounds........I sure hope I can get this gun running good both suppressed and unsuppressed but if not then I'll just shoot up my subsonic and be done with it (if indeed it is the issue which I still do not know).
