@Clapp @ArmadilloRancher @Jonaschuzzlewit @d0c40r0 @Chzikken_1486 @PraxisOfEvil @Turdicus .22 from my dads stand point years back. Stated the police uses .22 for some of their pistols because its high velocity.

9mm it said to have a little more stopping power but if your going for accuracy. 22 is still the standard for some pistols.

Not talking rifles, but you can probably see why .22 makes sense if thats the case.

Not to mention its light and you can hold more ammo
