The 2022-production SIG Sauer P220 Nitron R BSS CA variant brings the proven, full-size Classic Line .45 ACP to California shooters who want factory night sights, a loaded-chamber indicator, and a clean black-on-black finish. This pistol ships with ten magazines and upgraded snakeskin-pattern G10 panels that offer secure texture without adding bulk, all while retaining the P220’s trusted DA/SA trigger system and alloy frame.

What’s Included
- Gray SIG Sauer factory hard case
- SIG Sauer Classic Line Pistols owner’s manual

This CA roster P220 is built in the United States and marked with the 37C serial prefix, confirming 2022 manufacture. The slide’s Nitron finish resists corrosion and glare, while deep rear serrations aid positive manipulation even with gloves.
The alloy frame keeps weight manageable and incorporates SIG’s three-slot accessory rail for lights or lasers. A decocker lever safely lowers the external spurred hammer, and the automatic firing-pin block, safety-intercept notch, and trigger-bar disconnector provide multiple redundant safeties without a manual thumb lever.
SIGLITE tritium 3-dot night sights give a bold sight picture in low light. A loaded-chamber-indicator cut in the slide satisfies California requirements while offering instant visual confirmation of status.
The factory carbon-steel barrel measures 4.4 inches, pairing classic P220 accuracy with a balanced overall length. Combined with the crisp SA pull and smooth DA stroke, this pistol delivers duty-grade performance in a configuration fully compliant for California owners.
