Questions & Answers
Will this work with the Sig P320 AXG Scorpion? Expert Answer

It will not fit without an adapter. The P320 AXG Scorpion is machined to accept a Romeo1 PRO or Leupold Delta Point PRO. To install an RMR-pattern red dot like the Holosun 407/507 models requires an adapter that changes the mounting pattern of your slide.

Helpful Positive Review Holosun is awesome by Jeff585, Verified Owner, November 29, 2020
Shame on Trijicon for suing Holosun. They make an overall better product at a lower price. Shake awake, auto dim, "forever" battery life, side door for battery replacement. It is a great reflex sight at a reasonable price.

Helpful Positive Review Great Red Dot by WaltherPDP, Verified Owner, February 15, 2024
Easy to mount on a Walther PDP. Shoots perfect. Might be my favorite setup, hard to go back to iron sights. I never shot so fast or accurate until now. I ordered another one for my VP9.
