I recently purchased a Colt 1991A1 Combat Commander. I replaced the plastic trigger with a original colt s/s trigger and a metal mainspring housing and replaced the firing pin and recoil spring. That brought my groups tighter, but I noticed my shots are stringing up and down, not left and right. I read a thread in one of the posts a few days ago about someone else having this problem, but now I cannot find that post.
Can anyone help me with this problem? What do I need to do to fix this problem?
Is it a tuning, or a part replacement problem?
I am shooting 230 FMJ rem UMC, if that helps.
Any help would be appreciated!
