About this product

This is the original P365 micro compact with an optic cut slide and a Romeo-RS Compact red dot included. The 3.1 inch barrel sits under a Nitron finished stainless slide, and the standard fully textured polymer grip module keeps the gun small enough to carry every day of the year. XRAY3 day/night sights are installed for use without the dot.

The slide is cut for the Shield RMSc footprint, using the optic cut design patented by ZEV Technologies. The Romeo-RS Compact projects a 32 MOA circle with a 2 MOA red dot. Two 10 round steel magazines are included. The P365 is striker fired with a clean, crisp trigger and is rated for +P ammunition. The gun is 5.8 inches long, 1.1 inches wide and about 17.8 ounces, small enough to carry every day. Getting a dot in the box saves the hunt for a compatible optic and the work of mounting it.
