Sig P320, Sig Romeo Zero

This will allow you to mount your Sig Romeo Zero red dot directly on your Sig P320 slide. This program will leave the factory rear dovetail intact, and will machine the red dot deep enough that the integral iron sight on the Romeo will cowitness with the P320 factory iron sights. This will tap your slide to use the M4x.07 screws that came with your Sig Romeo Zero red dot. Screws may require fitting for length if you are installing the red dot yourself.
