I have written before about FTF,FTE issues with my Interarms PPKS. I polished the slide rails, the load ramp, and the entire chamber. I greased up the gun, and dis assembled the extractor and safety mechanism to be sure it was all in order. It was clean, all parts present, and the detentes in the safety were good. It was slipping into a partial, or full safety position during firing. I just ordered a full set of Wolff springs. They come in 14,15,16 & 17 lbs. The factory spring is 20lbs I believe. I got 1000 rounds of American Eagle at what would be $13 a box of 50. I figure they may not be a very strong load, requiring a weaker spring.

MY QUESTION (finally) is... which spring would you start with? The 17, and then the 16. 15 etc? Could 3 lbs make much of a difference? And if I step up to a hotter load (Cor-Bon), is a lighter spring going to cause a problem than?
