Questions & Answers
Will 507 K fit S&W MP with no wedge or modification ? Do I need the mount ?

Depending on the footprint, you'll need a mounting plate. Few guns and dots will direct mount and I would bet the K series would not. However, the 507C is better sized for a 15-shot carry gun. Do some research or you'll be disappointed.

will it fit a sig sauer p230? Expert Answer

The Holosun Ronin HS507COMP is not directly compatible with the P320. To mount this optic, you would need an adapter plate that converts your DPP cut slide to accept optics with the RMR footprint. Linked below is a plate that will allow you to do so. If you have a P320 with a Pro-Cut slide, an adapter plate is not required, it would be a direct fit.

Big Window by Badazz, Verified Owner, November 4, 2025
Went with the Ronin for the cool factor! Put my SRO to the side for a bit. This does take up alot of slide. Not for your carry gun. This is mostly for the range.

Works great on my Stoeger M3000 by Roger Keyes, Verified Owner, August 31, 2025
I got lucky and it was almost zeroed on my gun out of the box after I carefully mounted the 0.67in. radius base plate and then the holosun on top. I like 32 MOA ring for buckshot at 50 yds. Works great for slugs, too. I'm pretty sure it's my gun that...
