I've always liked the classic colt 1911s, but know they are tough to get in MA. So, was thinking of a build. My research says that Springfields are usually the preferred base in Ma, but also tough to get here. So, lets say I want a good classic style 1911, the only real deviation I guess would be adjustable sights, but outside classic. Internals don't need to be stock though, I want to optimize accuracy and reliability as much as one can practically balance them. So, what do I want. Base gun, trigger, barrel etc..?
