I am under the impression that some companies (Colt, Wilson) use a dedicated slide stop for their 9mm/38 super 1911's, while most other companies just use the 'stock' 45ACP slide stop for their 9mm/38 super guns?

Is there a substantial difference betweem the two types? I have a Colt Series 708 in 9mm and a Sistema Colt 45ACP and I do not see a substnatial difference in the two slide stops(?)

The part of the slide stop that hits the follower on the magazines is a bit wider on 45acp. Ive never tried a 9mm stop in a 45 or vise versa.
If you were putting a 45 stop in a 9mm you might need to do just a bit of fitting.

The smaller the caliber, the deeper the slide stop has to reach into the magwell. I have modified a Super slide stop to work in a .45, by removing material, so I don't think it will work the other way.

How big of a difference is there between them?

I've got 2 9mms and what I might believe to be a .45 and to see any difference in depth into the mag well, I just about need calipers.

It will also work using a .45 slide stop on a .38 super, however you may encounter problems with the magazine follower not pushing up on the slide stop when the mag is empty. You have have pick and choose the right magazine.

I have a .38 super that I built on a Olympic Arms frame with Caspian Arms stainless slide and I wanted an extended slide release but no one makes it for a super, I looked around for the best magazine follower / slide stop fit. I found that Mec-Gar is the best to use.

Spot on as usual.
The super / 9mm turns out to be about .020 deeper into the mag well than the 45.

Colt uses number on the inside to deleniate the slide stops.
1 is for 45 it sticks in .200
2 is for the 22 ace.
3 is for super and 9mm in reaches in .220
4 is for 10mm / 40

Springfield stamps 9 on the inside of there 9mm slide stop.

We just started making slide stops last week.
Machined from bar stock so we were doing research on them.
We saw a need for a traditional looking slide stop for 9mm and Supers.

thank you

Wilson Combat makes them.
