hi, I have 2 P3AT's gen 2 in our famly. My son's went through the same break-in period of 300 rounds in intervals and lubing and oiling after every range outting without ever a problem on either pistol. We both carry everyday and rely on it's flawless firing reliability. Both P3AT's have never failed us. Afer carrying them for several months in the same make pocket holster my son said let's see if there are any issues after carrying them and act as if it was a life or death situation. OFF TO THE RANGE ! I fired my entire mag without a problem and was quite pleased with the pistol and brought a smile to my face. He stepped up and after the first round fired the pistol jammed with the slide back and the next round facing level. He tried to pull back on the slide..no go..he released the clip and let the mag drop slightly and then the slide went forward and loaded the round. this round was fired and the next round did the same thing. The rest of the mag did fire. We both use the same ammo,Federal Hydro shok- Law Enforcement for carry and never had a single issue for over a year of use . He is now concerned that this weapon is not reliable as a SD pistol and has lost all faith. We switched to Critical Defense FTX , fired 2 mags each and all was fine. The CD ammo seemd to glide into the chamber and fired with les recoil. The problem still is when you need it will it be there for you? I told him that semi's are not flawless and you have to train yourself to react to any problem and always keep the firearm pointed at the BG. Sadly, this has greatly turned him from the P3AT security he has always felt and is thinking of a trusty revolver. I told him we will put another 100 rounds through it and see what happens. Expensive indeed!! Any ideas on how to make this more reliable after carrying for a few months ? I'll post back after we go back to the range tomorrow.
