Frequently Asked Questions
How does the MK25 differ from a standard P226?
The MK25 is the military-spec variant. Key differences include phosphate-coated internal parts for saltwater corrosion resistance, an optics-ready slide cut, the E2 grip, and the inclusion of three 15-round magazines. It’s built to a more rigorous standard.
What ammunition does it run best with?
Based on our extensive handling, this pistol runs flawlessly with standard 115gr and 124gr FMJ range ammunition. We did note one single hiccup during testing with a specific brand of 147gr subsonic load, but it has been 100% reliable with all other common defensive and training rounds.
Is the slide cut compatible with other red dots?
The slide is milled specifically for the SIG Sauer ROMEO1PRO footprint. To mount other popular micro red dots like the Trijicon RMR or Holosun 507C, you will need an adapter plate, which are widely available from several manufacturers.
