Frame will just say 22 cal even if it is a Magnum which the SN indicates it is. Mine is stamped .22 Cal. The cylinder does not say .22 Magnum like on the convertible models. When the 3 screws were made, they made them in 22 lr or 22 magnum.
But I have seen recievers with .22 Mag on them.That are from about the time this was made.I tried finding serial # close to this one.They say .22 Mag.Maybe I should just by the damn Colt Frontier and forget this SS
