I think the Wilson Combat Flat Wire Spring Kit is one of the best upgrades you can make to a Pro size gun. Just the ability to break the gun down without the need of any kind of tool is a good reason for going with it. The added spring life is another plus, the flat wire spring will outlast many conventional springs. We have quit a few members here using it and I've not heard one person say a negative thing to say about it.I was thinking about getting a Wilson Combat Flat-Wire Recoil Spring Kit, 4" Compact .45 ACP for Kimber Pro Carry II. Looking for some feedback.
Depending on how much you shoot that kit could pay for itself in the long run. One WCFWS will outlast 3 Wolf premium replacement springs. That's $10.95 vs $24.00.The 1st thing I bought for my new Pro Crimson Carry II was the Wilson 651 flat recoil spring kit. It was the best mod I bought. Just not dealing with that paper clip was worth 50 bucks to me, and it should perform better than what comes with the gun. Buy one, you won't regret it!
