I very much like the fit and finish of Sigs. But the Glock allows the shooter's hand to get so much higher up on the pistol - ie. more in line with the bore. I find Glocks to be a lot better about getting back on target quickly for a rapid second or third shot. The Beretta is another quality handgun - although the original Model 92 9MM is still the best, IMO. But of all of them, I can still shoot a customized Colt 1911 the best. May have more to do with the great single action trigger than anything.
