That's the great thing about 1911's, if you pick a good platform, all of the above are a great starting place. Anything that does'nt agree with you can be changed. Kind of like a small block chevrolet. The 1911 is the only gun I know of that in the end, may not have a single part it started with. Another good thing is all those spare parts can be built into another one. Example, I bought a Caspian wide body frame about 1990, then bought a SA 1991 a1 in 9mm, took the slide assembly, mounted bomar sights and put it on the wide body frame. Later took the SA lower and found a Colt siide in 45 acp, installed bomars and a Kart barrel, that's now my bulls eye gun. I keep buying parts, now I have 8 complete 1911's and 2 in progress, a Les Bauer matched slide and frame and something I always liked the looks of, a Safari Arms Matchmaster, stainless slide and frame. Throw in a .22 conversion kit and well, you see where I'm going. Don't worry Don, my first love has always been revolvers. At our club we used to have match called the BRT, stood for BIG ROUND THINGS, to our bottom feeder friends.
