9mm slide stop for 1911

I see slide stops for 1911 in ebay that are 9mm, anyone know what the difference is?

Dimensioned slightly different for the 9mm magazines

 I assumed that but what is slightly different? Looking to possibly use it in my .22 conversion.

About 0.025" longer on the portion that contacts the mag.

OK Thanks!!

Although they are marked with a #3 in the Colt, other manufacturers are not! S/A has (if not presently) ships their 9mm/38Sup with the same S/S used in their 45ACP. The 45 S/S may or may not work with 9mm mags it depends on the dimensions of the follower and how close it is to the S/S. Some followers can be "adjusted" to accommodate the 45 S/S reliably some not so much!

I have quite a few 1911 s/s pins for .45acp. Not interested in using the 9mm s/s pin in the 45acp slide. Looking for something slightly wider to fit German die cast .22 mags I fitted in my .22 conversion. I did bore a .203" hole in a 45acp s/s where the pin is so I have a hole. Works but if I release the slide with the mag inserted the s/s will climb over the tab. Wider will be better.
