A used Sig Sauer P220 Custom Shop Equinox in .45 ACP with a 4.5-inch barrel, from modern production. The alloy-frame double-action pistol carries a manual decocker, a tritium fiber optic front sight and a tritium rear sight. The matte black finish is set off by silver and high-polish accents, and the grips are textured wood. The bore is very good, the finish shows light marks and the overall condition is very good.

For a New Mexico owner this is a full-size .45 for the nightstand or the range rather than deep concealment. The decocker lets you lower the hammer on a loaded chamber, and the tritium sights glow for night use. If you carry it, the state concealed handgun license covers that, and a licensed buyer skips the seven-day waiting period at the dealer. With no registration in the state, the purchase stays between you and the dealer's federal paperwork.
