So i thought i would start a topic on this just for info. Here is the set-up:
I took a brand new Shield 9mm and installed an Apex Duty/Carry enhancement kit saturday (which by the way is a huge pain in the dick compared to working on a Glock or 1911). The kit consisted of a trigger, trigger spring, firing pin block plunger and spring and a new sear. I took it out to shoot yesterday to compare it against another shield with the stock trigger. The Apex Trigger is better but i am not sure its 149.00 and 2 hours of my life to install better but that's another topic. I put 5 or 6 mags of mixed 9mm ammo through the Apex Equipped Shield. The last round of the last mag went boom. Glad i was wearing glasses as i always do. The bullet went down range and the gun did not cycle fully the blown case was stove piped in the ejection port. The case ruptured at the thick part i assume at the feed ramp. The case is a +p Military Case. Many of the cases in this box were marked +p of several Mfg'ers. Wondering if +p cases have seen more stress to start with or if that even matters. The gun appears undamaged other than discoloration on the feed ramp. After taking it apart and visually inspecting it i ran another 3 mags worth of ammo thru it with no issues. So i think what i have is an ammo issue. Today i fully stripped it and looked at everything and even Magnafluxed the slide and Barrel finding no defects. I am looking for insight from all the smart people on here. Was it Ammo? Was it an out of battery ignition caused by the Apex Kit? Was it operator Error? ETC. ETC. The ammo i was using was BVAC HTM 9mm Reloads. I bought these not knowing they were reloads as they are in factory looking boxes and seem like factory loads. But upon inspection there mixed headstamp brass supposedly once fired. 115Gr FMJ. I am assuming that the installation of the APEX trigger kit did not contribute but i can't totally rule that out. Take an look at the pictures and see what you think. I obviously was a dumbass for buying and using this shitty BVAC Ammo. But in fairness i bought several cases and have shot more than 1000 rounds of this over the last 5 years with not issues. So maybe its an isolated issue albeit one that would not happen had i not bought this ammo i assume. Not sure if i should use the rest or save it for the Zombie Apocalypse for trade fodder.
