here is my walther p99 (not s&w) and my p22 (oops that is my wifes but i still shoot it allot). by the way my p22 shoots all the cheap ammo with no problems. i see allot of people stating problems with ammo.
so if you think the .40 S&W is the best round out there, my 10mm has one up on you. 180gr 1300fps, dang that is going to hurt
