So... does the drum mag fit the pistol as well? If so...
I think you can see where I am going with that.
yes it would fit the pistol , but because the "S&W" are made for the pistol and the rifle that is the problem .The drum is "made" for the Rifle by a different company . It is what the magazine is made for that the govt hangs there hat on . Pistol Mags are limited to 10 rounds rimfire or not
