It came with a 5 round and 10 round, I can put my Glock mags well in it and get a double stack 32 round, also except sig Smith and Wesson. This rifle will shoot 250 fps faster then any pistol, watched them shoot 240 grain shells 200 yards and blow threw a 2x4, got to remember this barrel has twist every 10 inches, might look cute, but with a hollow point no man or a white trail deer, Coyotes don't stand a chance, and yes, I will deer hunt with it regardless of what anyone thinks here, watch some video on it if there is any nay sayers.
