You're right, I wasn't even thinking of the Spanish guns. Damn school has me too tired to think right. At least tommorow's friday
Now to determine caliber. Is it an M-43 9mm (my guess is yes because 9mm is a prefered pocket caliber and an easily aquired blank), an M-40 .40 caliber (not too likely), or an M-45 .45 ACP (also an easy blank, bore diameter hard to determine)?
