Hello all, I just completed my Colt National Match pistol. I acquired the SS NM slide, barrel, & bushing from a friends late dad who use to be an Army armorer at Ft. Sam Houston, San Antonio Texas. The slide, barrel, and bushing were never used and not fitted. I fitted all of the parts, sanded all the factory lines out of the stainless steel slide, glass bead blasted it, and used a Foster SS Frame. I must admit this my first 1911 build, the hardest part of the build was fitting the slide to the frame and fitting the barrel. I want to get it check out by an experienced gunsmith and get the ok before I fire it.
