I spoke with a gunsmith, well known, about building a ground up 1911 for me. He uses Caspian frames, which are made from Pine Tree Castings. He says they're tougher than forged, He was a master gunsmith for the AMU, and speaks from experience. So, Caspian frame, or quality forged frame? Which do you prefer, and why? I'd ask opinions here on this issue, and it would be great if you could refer to experience rather than what you just read or heard about the subject "second hand". Thanks. BTW, I'm probably getting this build done as soon as we can determine the specs I want - it'll take a year to get done - better than the 5 years on some lists I guess. Wanna kill these ads? We can help!
