Just a six digit serial on the right side of the frame, barrel and slide, no symbol, dashes or letters included. First two numbers are "16" so it's not a year clue.

Look at the small space above the extractor and you will find 2 stamped numbers. This is the date of manufacture, the last 2 digits of the date. thus, 01 is 2001 manufacture. Hope this helps.

The serial number L3030 is on both the barrel and frame.
