The P365 XL X-Series configuration delivers a 3.7 in barrel and extended slide length for a longer sight radius while maintaining a slim profile. The slide is optics-ready with an RMSc footprint and includes a cover plate, offering straightforward compatibility with micro red dots that share this pattern.
The flat-faced trigger provides a consistent striker-fired break, and this model has no external manual safety. The X-Series polymer grip module adds an extended beavertail and a mild magwell flare, with molded texture for confident control. A SIG proprietary single-slot accessory rail supports compact lights or lasers designed for this interface.
Sighting is handled by tritium 3-dot night sights, with a high-visibility green ring on the front sight and a dovetail-mounted tritium rear. Capacity is 12+1 with the included factory magazines, matching the XL’s carry-focused design.
Construction includes a carbon steel barrel, stainless steel receiver, and a Nitron-finished slide in black. Overall dimensions are 6.6 in long, 4.8 in high, and 1.1 in wide, with an unloaded weight of approximately 20.7 oz. Made in the USA, this example is the 365XL-9-BXR3P configuration.
