Not to get too off topic here, but my problem with short 1911s in 45 ACP is reliability. Just observing a few things about the pistol makes you realize the operating clearances needed for reliability have been completely compromised. The magazine springs are wrong, breechface overtravel is zero, and timing of the cycling event has zero room for error.
At some point it will be a club when you need it to go bang. I’d rather have a gun than a club.
