Sig Sauer P365 Custom Works Fire Control 9mm Luger .380 ACP Gold Nitride

The Sig Sauer P365 Custom Works Fire Control Unit (FCU) is a clean upgrade for shooters who want to build a tailored micro-compact pistol, and because this FCU is an FFL item it must be transferred through a Federal Firearms Licensee; this Custom Works unit brings a Titanium Nitride frame and Gold Nitride finish to the P365 platform and includes a flat face Titanium Nitride trigger and a custom FCU serial number, enabling you to legally register a high-end core component while keeping full compatibility with all 9mm P365 parts, magazines, slides, barrels and optics. For concealed carry use the reduced profile of the P365 series combined with the durable Gold Nitride coating resists wear from daily carry and holster use, while the flat face trigger offers a consistent break that many shooters prefer for controlled follow-up shots during training, competition, or duty overlap. Gunsmiths and builders will appreciate that this FCU supports both 9mm Luger and .380 ACP conversions within the P365 family, allowing you to configure calibers, grip modules and sighting options without replacing the serialized core. If you're assembling a personalized carry pistol, a backup gun for service, or a custom competition micro-compact, this Sig Sauer Custom Works FCU gives you the legal serialized foundation and premium materials to build a tailored P365 that performs on the street, the range, and in the hands of a responsible owner.
