This Equinox edition comes from SIG Sauer’s Custom Works program, meaning each pistol was hand-selected for fit and finish before receiving the unique brushed-stainless highlights and stripe milling that define the series. The contrast not only looks striking but also makes the front serrations stand out for easy manipulation.
Functionally, the pistol retains the proven P226 double-action/single-action system with an exposed hammer and a frame-mounted decocking lever. The short-reset trigger (SRT) speeds up follow-up shots, giving shooters a crisp, consistent break on single-action pulls.
An aluminum-alloy frame keeps weight to a manageable 34 ounces while still housing a four-slot Picatinny rail for lights or lasers. The full-size grip wears checkered polymer panels that anchor the gun securely, even during rapid strings of fire.
SIG X-Ray3 night sights—green fiber-optic/tritium front paired with two-dot tritium rear—deliver a bright sight picture in daylight and glow after dark, reinforcing the pistol’s all-day readiness. Coupled with 20+1 capacity using the included extended magazine, this Equinox brings modern capability to a collectible package.
