The SRT suppressed Camp Carbines in 45 are very nice. Here are a couple of pictures of my Camp Carbine. The gun is quiet and really fun to shoot. Doug (at SRT Arms) is a nice guy. The first picture is with the original wood stock and the second is with a folding stock. The 45 Marlin Camp Carbine uses Colt magazines. One thing that you should think about is replacing the recoil spring with a heavier recoil spring to decrease the bolt openning speed. I replaced the stock 11 lb recoil spring with a 21 lb Wolff spring and it has reduced the ejection port sound (not objectionable, but you get it on any suppressed semi auto) plus it is probably kinder to the receiver and stock. The suppressor itself is quite quiet perhaps in the same sound range as a .22 lr muzzle suppressed pistol although I think the duration of the sound is a greater in the Camp 45.
