This P211 GTO uses a single-action, hammer-fired system on a 1911-style platform with an ambidextrous thumb safety and a beavertail grip safety. The flat, skeletonized trigger and skeletonized commander-style hammer complete the control set for a crisp, familiar manual of arms.

A steel frame supports a separate alloy double-stack grip module, delivering a 23+1 capacity with SIG P320-pattern steel magazines. A flared silver magazine well aids reloads, while aggressive-texture grips offer secure purchase.
