Went fishing today at a buddies place on a private lake. (Caught 24 giant slab sided crappie!) My friend wanted to try my P3AT, as he's thinking about buying one himself. So I brought it along with a few boxes of WWB 115 gr and 3 boxes of Cor-Bon 90 gr. Self Defense JHP. I carry my 3AT loaded the the Cor-Bon, thought I'd let him shoot a few to check them out. He shot 5 mags of WWB with out a hitch so we loaded up the Cor-bons and he ran 2 mags with no trouble. On the 3rd mag---3rd round, instead of a BANG he got a little pop...like from a cap gun. I hollered at him to stop and we took the pistol to a table to check it out. Yup, bullet stuck about halfway in the barrel. Stripped the gun and used a cleaning rod to drive it out. Cleaned the pistol and oiled it back up...ran another few mags thru it with no problems. Now what? This is the ammo I'm depending my life on? I can see maybe a squib in cheap WWB ammo, but in a supposedly high quality self defense round? Any comments?
