This P220 is part of SIG's Custom Works Nightmare series and is designated 1 of 500. The case label is dated 18-NOV-2020, and the pistol ships with Custom Works presentation items, including the challenge coin and certification card.
The build pairs a stainless slide under a black Nitron finish with an alloy frame finished in black hard-coat anodizing. Details include rear-only cocking serrations, a SIG Custom Works medallion on the slide, contrasting nickel/silver-finish controls, and vertical serrations on the front strap. Black textured grip panels wear the SIG SAUER logo.
Factory 3-dot tritium night sights are installed, with a high-visibility green-ring front sight stamped TG-H3 and a tritium rear. The action is DA/SA and hammer-fired with a decocker and a curved trigger for a traditional P22X manual of arms.
Chambered in .45 ACP, the pistol uses a 4.4 in carbon-steel barrel and feeds from 8-round magazines for an 8+1 capacity. A single-slot SIG-style accessory rail on the dust cover supports compatible lights or lasers. The included magazines have polymer base pads and numbered witness holes 1–8.
