The game has incorrect .45 ACP ammo data. .45 ACP ammo is about 30% more powerful than 9mm, but in the game, 9mm guns do more damage than .45 ammo guns. This is very unrealistic. It should be like this: .45 ammo has more damage, but more recoil and a smaller magazine. 9mm ammo guns have less damage, but a bigger magazine and less recoil. Right now, the game has it the opposite, making .45 ammo guns unusable.
