9mm is not truly "Taboo" in a 1911, and in fact I have one, but my experience has been that it's far less finicky in .45 ACP as both God and John Moses Browning intended.casp625 wrote: My other consideration is now dealing with caliber choice. I'm starting to think I should go with the 9mm 1911 instead of the 45ACP considering I have a bunch of 9mm ammo at home. Or is this taboo for a 1911
All kidding aside, a 9mm 1911 is a nice gun. My only issue is finding the "right" extra mags for them that work well with the ammo you choose. 1911's can be touchy about anything except factory ammo, and 9mm's display this behavior even more so.
