After long-ago experience with a gold cup 1911 that kicked like a mule, and did not dependably feed semi wadcutters (perhaps due to it's tighter target oriented tolerances?) I don't see why folks wouldn't take advantage of newer plastic 40cal.
Or if it is for urban home defense or whatever, cut the chance for collateral damage and lawsuits with even a humble 9mm, 380, or .410 buckshot pistol. The last two I would have never considered except for a recent program with detailed examination of ballistics and debunking their bad reputations.
The 9mm seems so arbitrary... it was the max size that the luger designer could bore out his barrel when told his bore size wasn't enough. But it's popular cartridges have so many variations. Aforesaid program found some super effective variety, one of those with plastic filled hollowpoint. Our police dept uses wimpy depowered ones, which saves a lot of lawsuits. I don't know if you can get a certain russian police version which has a body armor piercing core and a beyond the limits brass size and powder charge.
