I've seen Colt's 1991A1 GMs chambered in .45 ACP, .38 Super, and 9mm P.
But I've heard rumors of 1991A1 production in .40 S&W and 9x23. Has anyone seen these or other calibers in this particular model? Just curious!
BTW, the most unusual chambering in a 1911 I've encountered was a Colt's Series 70 GM in 9mm Steyr. About 15 years ago I had a probably once-in-a-lifetime chance to buy one NIB and passed on it. One of the many guns I regret not buying!
