I have owned and carried Beretta 92s, several makes of 1911s, Sig 226s, 229s, and 220s, and Springfield XDs.
If you put a Sig 220, quality made carry 1911, or Springfield XD in a box and had me draw one out blindfolded, I'd be fine with it. I could say the same of any of those makes in a .40 or even .357 Sig....but I'd prefer to choose from box#1 full of .45s. :mrgreen:
Springfield has a new compact version of the XD in .45 out that should be more concealable than the full sized version, also.
