This SAO P226 eliminates the decocker in favor of an ambidextrous manual safety and a tuned single-action-only fire control group with a flat trigger. The external spurred hammer and extended beavertail support confident manual control.
The ZEV slide incorporates aggressive front and rear cocking serrations along with slide lightening windows/cuts. A tall fiber-optic front sight provides a bright focal point, and the factory RXP package equips a mounted SIG Sauer ROMEO1PRO micro red dot with a red dot reticle.
The 4.9-inch barrel is threaded 1/2x28 RH and capped with a knurled thread protector. The full-size aluminum-alloy frame is railed on the dustcover for accessories and wears G10 textured grip panels with the ZEV logo for a secure hold.
This model is marked Newington, NH, USA, and carries the Custom Works/ZEV collaboration details and factory model code E26R-9-ZEV-SAO-TB-RXP. It ships with two 15-round magazines and the labeled SIG factory case; note that the factory label lists three 15-round magazines, so one is not included.
