I really dislike plastic mainspring housings on 1911's therefore I generally change them to a steel one when I get a chance. I have done this on at 3-4 of my Colts without any problems. Anyway I pulled the plastic MSH off of my recent production Kimber fullsize and replaced it with a steel one. One problem, the hammer will no longer cock. I can pull the hammer back but it will not stay cocked. I tried replace the factory standard MSH with the same results. What am I doing wrong?
