I have 2 frames, and several barrels. one is the 223 14", and it shoots quite well. also have a 21" barrel for it, and that really shoots great. others are a 45/410 and a 35 herret, which also shoots good. they are fun, and the carbine is really handy for a rifle. as was mentioned, start out with a pistol to be legal. good luck if you get one.
