    The barrel should be marked with the caliber and type of ammunition required. might have the one you need. There are other reputable one line magazine sellers also. Good Luck.

    If you have a set of calipers, you could always measure the inside diameter of the barrel. .40 cal = .40in and the 9mm = .35. Both are approximate depending if you land on or off a land or groove.
