I've wanted a 45 acp carbine for quite some time, almost pickup a Thompson more than a few times. Anyway, last October I purchased a JRC Marine takedown 45acp. AR15 style, 16" stainless barrel and all electro less nickel finish. Uses Glock 21 mags. The fit and finish is perfect. This thing is a blast to shoot. I've put about 2600 rounds through it, 200 factory and the remainder my handloads. Two stovepipes from the first mag the rest is perfect. The round coming out of a 16" barrel is sooo quiet some asked if it's suppressed. At 50 yards it cuts out the center of the target. Past 50 yards that big fat round starts to wander. I'm happy!
