Bought a PF-9 that was made back in 2008 according to Kel-Tec. It came with the polymer mag release so that was the first thing I replaced. It was dropping mags with every shot just about. Kel-Tec sent me a metal one for free and I replaced the mag release, spring and everything was all good. I also replaced the recoil rod/spring when I first got it. I was bringing the pistol to the range at least once a week in attempt to get used to the recoil this gun has. Yesterday I got through about 6 rounds before the gun sheared off the disassembly rod and locked up. I'm guessing it might have walked out on it's own or I didn't have it in place correctly from the last cleaning. I was able to get the broken rod out and unlock the slide. I came home and ordered a new rod and threw in the metal recoil rod as well. Soon as the rod/pin gets here, we'll be back in action. I do have the 8 round mag extension as well. Thing is, guy at the gun range told me this gun really isn't made to be shot very often. I know it's an ideal CCW gun but I enjoy shooting it along with my other pistols. I'm putting 50-100 rounds through it every week or so. Is that too much? Should I take it easier on the gun? I feel like the old assembly rod was beat up a bit and fragile. What do you guys think? Also is the metal recoil rod worth using?
