Upgrade your compact handgun with the superior Wilson Combat Bullet Proof compact spring kit!

This set includes a stainless steel full-length recoil guide rod and an extremely reliable chrome silicon 22-pound flat wire spring that lasts much longer than regular compact recoil springs.

With this kit, you can guarantee better performance for your pistol every time you pull the trigger!

The innovative flat wire design permits for a longer free length with more coils while preserving tension better than round wire springs - plus you save time as the guide rod is already prepped to fit compact barrel lugs and link.

Both at-home or field applications make it an easy solution for any problem you may have.

"Excellent upgrade for my Kimber shoots more smooth and no more tool to disassemble. Love it"

"Perfect Replacement for my Kimber Classic Carry Pro. Fit and Finish is top notch from Wilson Combat. No longer need to use the Kimber take down tool. The flat wire spring is a little noisy compared to factory, but longer spring life is the reason for purchase!"

"Just made the purchase and fnished my day at the range. This out performs the Original Mfg recoil spring and guide rod system No more Hicups and no more paper clips to disassemble my Kimber Pro Carry 2"
