Sig Sauer P365 Cal-X Kit 9mm 4.3" Optics-Cut Conversion Kit

The Sig Sauer P365 Cal-X Kit converts your platform into a longer-barrel, optics-ready 9mm pistol in one convenient package. Built for shooters who want improved sight radius, boosted velocity, and instant red-dot capability without buying a whole new gun, the Cal-X Kit includes a 4.3" threaded/port-compatible barrel, two magazines, and an optics-cut slide - giving you an upgraded carry or range setup with minimal fuss. This kit bridges the gap between compact carry and enhanced shootability: the 4.3" barrel increases muzzle velocity and sight radius for better accuracy, while the optics-cut slide accepts popular micro-red dots for faster target acquisition. Shipping with two magazines makes it range-ready, and the conversion approach keeps costs and training time down compared with swapping platforms. It's an ideal upgrade for P365 owners who want a more capable pistol for range, competition, or duty applications.Specifications:Platform: Sig Sauer P365 Cal-X Kit Caliber: 9mmBarrel: 4.3" Slide: Optics-cut for micro reflex sights Magazines: 1-21rd Magazine and 1-17rd MagazineFinish: Black
