So I finally got around to cleaning my 1911, and while cleaning the slide, I noticed a number scratched into the underside of the slide, near the rear. I've never seen that before but I noticed a Springfield TRP on the EE has the same thing. Is this just a Springfield thing and what does it mean?
Also, in case it matters, it's a custom 1911 with a Springfield base
