Hello and thanks for operating what looks like a very friendly and informative forum. I have recently purchased a 5906 round trigger guard 9mm at a local gun show. I know it was a police issue weapon by an added engraved serial number. What I am hoping for is a birthday for this pistol serial is VYY831* . I know this isn't as old as alot of the guns I've read on this thread but would love to know. Thanks in advance. I looked in the Semi-auto section and could not find a similar thread so sorry if i am posting this in the wrong section.
