ok, so i'm not necessarily going all Glock, see i'm going to get another Mech Tech CCU (carbine conversion unit). I've been considering the 357 SIG with the 16.5" barrel as being a good choice but i'm also looking at the straight 40 S&W, the 45 ACP or even the 10mm. Any thought from the masses? P.S. I'm also posting this on the Mech Tech sight forum, incase anybody was curious.
