I've got the Hi Point 995TS and I chose it because its a heavy bullet and the 16.5" barrel gives it 200 FPS more speed, and 9mm is a NATO round. That means, if I run out of ammo on the battlefield, there's a pretty good chance I can find some just laying around. I don't have a 9mm pistol, but if I ever get one, I'm ready to go. Would I ever say that 9mm is better than a 10mm? Nope, but I'd say its a lot more convenient. I asked a friend, who is a SEAL, just how lethal the 9mm carbine would be at 300 yards. He said that he wouldn't want to be standing in front of it at 300 yards.
