When I bought my HC/Green P3AT a while back from another KTOG member it came to me with the infamous frame grip bulge. How it got this way I do not know. I took the gun completely apart, including removing the frame from the grip, to clean and inspect. While it was apart I gently squeezed the grip in a clamp for a couple of days and it seemed to return to its proper shape. I reassembled as usual and all was good. Today I took it out to the range. On about the 10th round of some old Ranger T ammo I had my first ever squib round. I heard the primer pop but no bang. I field stripped the gun to inspect and noticed the take down spring was out of its place and bulging the grip again. Oh, and the bullet was still in the barrel. The range officer took it back to the shop and removed it for me. Nice guy! No KB this time. Anyway, is it possible that the take down pin spring popped out during recoil. Or is it more likely that it popped out when I pulled out the take down pin to inspect. This has never happened to me before. When I take it apart tomorrow, what should I look for to indicate (or not) that the frame is damaged? Is there a permanent fix I can do short of sending it back to KT? I did a search on this and it seems that most of the time the frame bulge occurs when removing the takedown out. And it appears that this is often solved by pressing down on either side of the grip when removing the pin. Sounds easy enough if this is all there is to it. Just wondering if there is some magical KTOG mod one of you guys have discovered to prevent this from happening again. And, after reassembling the gun (with the bulge) I fired another 7 rounds of that old Ranger T ammo. Got my second ever squib round on the last try. This time the bullet cleared the barrel though. Both times the unburnt ammo was a real mess.
