I have had a few P320 in my time but can't remember what this slide release fits.

Any clues, it does not work with my 320 in 45acp due to the grip area notch?

It's the slide stop lever for the P250 and early P320.

They later switched to a version with lower profile forward-projecting nubs.


This old style slide stop only works with old style grip modules. The new smaller style of slide stop works with both old and new grip modules.

That is it. Thank you!!!

I have a slide stop new in bag from Sig, 9mm, 357 and .40

The slide stop for my 45acp has the same dimensions inside and out but they list that the 9,357 and 40 stuff does not work in the 45acp grip modules.

how different are they?
