Hi everyone. If you have a semiauto pistol caliber carbine, please join in & tell me the good & bad points of your selection. Whats out there? The Marlin camp 9 / 45. The Ruger 9 / 40 (not the older 44 mag semi auto). The overpriced but cool HK UMPs and MPs. The Beretta carbine. Which one is best overall. Thanks for everyone's input.
