Serial number(s) location question

[Bigtanker]

I see several makes of guns that have the serial number several different places on the gun. XDm's have it on the slide, frame and barrel. Which one do our go by?

The reason I ask is if I bought a XDm compact and put a long slide from a full size XDm on it and the other parts are burnt up in a fire, lost on in a boating accident or whatever, which number is correct?

26 U.S.C. § 5842 and 27 CFR § 479.102. 1. SERIAL NUMBER. Must be conspicuously engraved, cast or stamped (impressed) on the firearm frame or receiver.

 

[JettaKnight]

The receiver is the part that matters. Therefore for your XDm, it's the one on the frame that is the serial number of the firearm.


FWIW, it's common to get Mosin Nagants with mixed serial numbers. Usually the numbers on the other parts will be stamped over or changed with an electropencil.
