Can you post a link to this video? I GOOGLED but couldn't find it.

I use a Surefire XC1 and it fits great on my 320C. I also bought a couple 21 rounders and found the XGrip adapter I use on my full size mags works well on the 21 rounders for use in the Compact model.

Glad this worked out for you. I have found the 320 just plain works for my hand better than most other guns. I might need one more if the fix works out.

A very light sanding on the rail edges might make light installation easier. I had to do this on my first P320c but not on my second P320c. I use an INSIGHT M6X on mine.

I put an InForce APL on my P320F .45 ACP. Fit fine. Never occurred to me it wouldn't.

None of my nine different P320 grip modules have any issues fitting rail accessories, including TLR-1, TLR-3, and X-300 lights.

Sounds like it's an issue with the M3 light, not the P320 rail. Unless you happened to get a P320 grip module that has some sort of molding defect on the rail.
