This may sound like a dumb question, but one of you guys may now the answer. Last night, I was cleaning my latest SP2022 in .40 S&W to get her ready for the range. When I was wiping the inside of the slide I saw stampings I did not remember seeing on my Sp2022 9mmP. The stamps are on the inside of the slide near the muzzle. I did not write them down and can't remember them, but they are two lines; the top line has LI?? (letters) and the lower has 4 or 5 numbers. Any idea what these mean? ?

Interesting. I think that all that I've seen in my 9 was some dots. I'll have to look next time I clean it.

OK, I am home this morning and the stamp on the inside of the slide is:
Top Line - AL04 Bottom Line - 0380 09
None of the number seen to correspond with the date of mfg. which is 12 June 2012. This is the date on the box.

I have two rows of 3 dots located in the milled pocket at the muzzle end. They look to be milled and not stamped. Does this compare to your 9mm? Also is your 9 an external extractor and your .40 an internal one. It could be the result of different machining processes. Or if there is a significant difference in the build dates of your 9 and your .40. My 9 was built Sept 2011.

kennyd,
I got my 9mmP 2022 out of the vault and removed the slide. There are no markings whatsoever in the milled pocket, and it was manufacturd in October 2011. The Extractor is external.
The .40 S&W has the internal Extractor. and built in June 2012. I did not think I remembered seeing anything stamped inside the slide on the 9mmP, but wanted to make sure.
It just seems strange to have these numbers actually stamped in place. It certainly means something to Sig I am sure, but what??? I am an inquisitive person for markings on firearms, LOL.

Can you guys with the SP2022 in .40 S&W check the inside of your slides for any markings I am showing in my pistol? This is driving me "nuts" not knowing what the heck this stamp/s denote. I really think I am to "anal" about this, LOL!
