I hope this hasn't been beaten to death in other posts (if so, just let me know) but what are the stock springs in a Kimber Custom Classic? I am at the point of replacing the important ones in mine and don't want to deviate too much from the stock springs.

The recoil spring seems stock at about 16#. I am wondering about the firing pin spring and mainspring. I usually use an extra power firing pin spring and a reduced power mainspring (19#) on my Colts and my one Wilson. Does Kimber use similar spring weights or should I expect to have to recalibrate the pistol with new springs?

There is nothing in the manual about spring weights.

Thanks,

Tim

There is nothing special about the springs used in the Kimber Custom Classic, it is the pistols with the shorter (less than 5 inches) slide lengths where different spring rates matter in a Kimber.

You are correct Kimbers come with a 16# recoil spring, though most of us will probably suggest replacing it with an 18.5# spring. As the 16# spring is really not enough for ammo that may be loaded hotter than standard velocity. The extra power firing pin spring is a good idea, and Wolf Gunsprings sends one with their recoil springs. Since you have a Wilson and more than one Colt you probably already know this. So your current practice with your other pistols will work just fine.

I hope this helps.

I agree with Str8_Shot. After 600 rounds fired on my Eclipse, I was still having FTF's with the stock Kimber 16 pound spring. I switched to a Wilson 18.5 pound and I haven't had a single FTF since.

I shoot 230 ball, and I put a Wilson kit in mine. 18# recoil, 16# hammer(main), and a firing pin spring(#?) and am quite happy. Also added a shock buff. This kit also came with a softer recoil spring for lighter ammo. I replace the recoil spring every 1000rds (more often than needed). To me, a 'fresh' recoil spring is pretty important, and the stock spring is too short, and not heavy enough for constant 230 shooting. It's sort of 'all purpose'. --HD

Thanks a bunch. I just finished putting an 18 1/2# recoil spring, 19# mainspring and extra power firing pin spring in the Kimber and it is feeding better than ever.

Thanks,

Tim
