my buddy has a rock island 70's series 1911 and he would like to upgrade the grip safety I think the gun was made or sold by numrich arms.
I would like to update some internals trigger sear and combat hammer and sear spring : any one know the grip safety radius on a rock island?
Are they the same as the mil-spec .220 :wavey:
