The SIG 1911 Equinox, a Custom Works offering, will only produce 500 pistols.

SIG Sauer just launched its latest Custom Works offering, and it’s a good one. The SIG 1911 Equinox delivers a well-appointed, two-tone full-size 1911 featuring an impressive array of components. And this one comes in an extremely limited run of 500 pistols.

First Look at the SIG 1911 Equinox

The limited-edition Equinox comes chambered in .45 Auto only. It features a black anodized metal frame and also a Nitron stainless steel slide with custom machined side. The resulting two-tone finish is quite the looker.

The pistol comes equipped with SIGLITE Night Sights and Hogue classic contour SL G-10 grips. Exclusive SIG Custom Works features includes logo engraving on the slide. Meanwhile, a premium Negrini SIG Custom Works case, challenge coin and certificate of authenticity round out this incredible package. We included the full specs below.

“It’s a beautiful pistol,” said SIG’s Phil Strader. “The 1911 Custom Works Equinox: a great single-action-only pistol in .45 ACP. Only making 500, so make sure you get on these as quick as you can.”

We’ve reported before on the quality work released under the SIG Custom Works brand. From P320 fire control units to P226 and P229 Equinox pistols, the brand is making its mark. Now the SIG 1911 Equinox comes with a limited release. With only 500 made, this one is likely to sell out extremely fast. For even more info, please visit
