Converting Colt 1991A1 .45 ACP to 9mm?
since you can convert a 1911 .45acp pistol to a 22 conversion, is it possible that i could convert my colt commander 1991A1 (or any other full sized framed 45 auto) into a 9mm conversion? if so could anyone let me know what companies to go through or what websites to begin with. any info on this would be greatly appreciated.

There will be some experts along with the rest of the details shortly I'm sure. Basically you need a 9mm (or 38 Super) slide and change the ejector on the frame of the 45 to 9mm/38 Super. Sometimes they work, sometimes they need a bit of hand fitting. And a 9mm magazine of course. Seems like an easy thing to do but isn't as simple as putting on a 22 conversion unit. 0 -
You need to change to a 9mm ejector and get the upper assy. and magazine. Them hope they don't need much 'smithing to feed. 0 -
Actually, unlike the Government Model, Commanders use the same width ejector for all calibers. You might have to go to a longer one, but maybe not.
But you must have a new barrel, slide, magazine, and all small upper parts.
Then hope the .45 feed ramp is not too deep to handle the shorter cartridge. A friend of mine has a 9mm upper on a Gold Cup frame that was shooting ok today but has given him a lot of trouble getting it that way.0
