If you are using a Kel-Tec P-32, please make sure you test the gun when loaded 7+1. I believe you will find, as I did, that the 9 lb. factory recoil springs are insufficient when there are 7 rounds in the magazine and (as happens about 1/3 to 1/2 the time) the rim of the top round is in the groove of the round below it. 11 lb. Wolff recoil springs are a necessity with this gun.
The extra power firing pin spring that comes with the recoil springs is also a good idea. My factory firing pin spring was worthless after about 1,000 rounds. Just make sure you back out the firing pin screw 1/4 turn after you put it all the way back in so the pin can move freely, and loctite it in place.
With those exceptions, my P-32 has been a very reliable gun, and is the only pocket pistol above .22 or .25 caliber I have ever seen that has truly comfortable recoil.
