You are probably going to have a problem finding either of those guns.
There are some 1911s you might find.
I have had pretty good luck finding Smith and Wesson E series and Pro series in .45 or 9mm.
Also have had pretty good luck finding both the Ruger SR1911 and the CMD size. The Rugers are not finished as well as the others but the guns shoot fine and mine are reliable.
I have a couple of Dan Wessons but you will have a problem finding any of those unless you find some used ones.
I see an occasional Ed Brown show up at the LGS but they are not cheap.
Good luck trying to find the one that suits you.
