Limited to just 500 guns, this Equinox Custom Works release occupies a special place in SIG Sauer’s catalog. Each pistol falls within the 54E05xxxx–54E07xxxx serial range and was assembled by the Custom Works team for enhanced fit and finish.
The signature Equinox treatment pairs a brushed stainless slide with Nitron-black flats and polished bevels, creating sharp visual contrast without sacrificing durability. Nickel-finished external controls complement the two-tone look and resist corrosion.
Performance features include a solid aluminum single-action trigger, skeletonized hammer, and 25 lpi checkering on both the front strap and mainspring housing for secure purchase. An integral, blended magazine funnel streamlines reloads while preserving the classic accessory-rail-free 1911 profile.
Factory-installed SIGLITE tritium night sights offer a clear three-dot sight picture in any lighting. Front and rear angled cocking serrations enhance slide manipulation, and the upswept beavertail grip safety with memory bump promotes a consistent, high grip.
