Sig p320 .45 grip module question.

A year ago I purchased a compact 320 in .45. Small grip module. I purchased a full size slide. So I need a full size small grip module, that will accept the gen 1 large slide stop. I can’t find one. Called sig, don’t have any. I will not change to the smaller slide stop. Not going to happen. I have 2 other p320s in 9mm with the large slide stop, I prefer it.

So.. has anyone taken a grip module meant for the smaller slide stop and modded it for the larger slide stop?

You will get more precise replies, but a lot of folks just take a Dremel to them to make cuts or openings bigger.

Thank you. I figured as much. Just hesitant to do that without asking for info first.

And keep watching the Sig site for .45 grip modules to go on sale. I just got a compact grip for 12 bucks. You can afford to grind the crap out of a 12 dollar grip!

Good advice. I don’t think sig makes a
Gen 1 frame for the .45
