This guy used a 28 LBS. I have the firing spring that was included with the 28 LBS recoil spring installed but I was thinking of using a 22 lb mainspring.
Even with the 28 LBS Wolfe recoil spring the Full size kimber will feed 45 auto and super loads with no issues.
Also which flat firing pin stop do I need for my Kimber USA TEAM MATCH?
Midway stops what say you?
