Hi everyone. I'm new here. I have a Kel-tec P-3AT that has about 150-200 rounds through it...never a hiccup. Well today at the range I was shooting the Kel-tec and my buddy was shooting his new Ruger LCP. His LCP was having trouble feeding the Magtech ball ammo he had purchased to break it in. I traded him some of my Winchester white box ball ammo for some of the Magtech. The LCP loved the WWB and functioned flawlessly from there on. I ran one mag of the Magtech through with no problems but then on the fourth round of the second mag all hell broke loose. I'm not sure what happened but the entire polymer frame, inner rails, slide, and barrel of the gun are destroyed. At this point I am leaning towards the ammo as being at fault but who knows? I do know that the shot before this one hit the target so there was no squib round in the barrel. The spent casing is still trapped in the chamber. Thankfully, I wasn't hurt. Anyone have any ideas as to what might have caused this? Other than too much powder maybe? Thanks ahead of time.
