The recoil spring is working better now that I replaced the plastic guide rod with a black stainless one. I have a complete selection of recoil and firing pin springs from Wolff for my LCP which will work if I decide to replace the spring in the P32. I read Fluff & Buff on one of the KT forums and many the older KT's needed polishing of the feed ramp, chamber and the face of the breech. Evidently, tolerances on the Gen-1 pistols was inconsistent.
I ran another 50 rounds through it today and had 4 misfeeds in the first 25 and none in the last 25. I bought another 100 rounds of different brands and will test again over the weekend. If it misfeeds at all this weekend, I plan on polishing the face of the breech a bit more.
The gen2 came out in 2005/06 ish so that spring is at least 10 years old at this point, no way it's still at factory strength.
