Frequently Asked Questions
Is this pistol optics-ready?
Yes. The slide is cut for the SIG ROMEO1PRO and Leupold DeltaPoint Pro footprints. The rear sight is mounted on a removable plate, allowing for direct optic mounting without an adapter.
Can I change the sights?
Absolutely. Our staff has confirmed the slide’s dovetail works with both factory SIG and aftermarket sights from major brands like Trijicon and AmeriGlo.
What makes the Legion different?
The Legion series includes premium upgrades. The key here is the TXG tungsten-infused grip module, which adds substantial weight low in the frame to dramatically improve stability and recoil management over a standard polymer frame.
