I have what I believe is a M & P .38, 5-inch barrel. What gives with the numbers? The crane and frame behind the crane are stamped with five digit numbers that match. The underside of the barrel (beneath the ejector rod) and the bottom grip strap are stamped with matching numbers also, but these are a six-digit number, starting 313XXX. The barrel number is preceded with "B."
Which numbers are the serial numbers, and is anyone able to offer a manufacturing date based on these numbers? What is the formal model name of this revolver, Model 10 or Military and Police,or ??? Is the model name marked at a hidden place?
Thanks.
