Its another one of those "you gotta reload" cartridges"10mm, it gave us .40S&W
Despite everyone always saying "I wish it came in 10mm" , they do not in fact sell. Most guys who have one never shoot them due to cost of the ammo, and properly loaded 10mm is relatively hard to find at not obsene prices.
It's an interesting cartridge absolutely, but it just annoys the hell out of me.
