Questions & Answers
will this fit the sig p365xl comp slide? I am looking to change my standard sig p365xl slide out with the comp version that requires a p365 barrel. Manufacturer Answer

This barrel is for uses in standard sized P365's, we haven't specifically tested it in a P365xl comp, but if it calls for the standard length barrel then yes this should work. Thanks!

Product Info for Grey Ghost Precision Match SIG P365 Full Size Non-Threaded Pistol Barrel

With the rapid growth of the SIG P365 market share over the past couple years it became necessary to maximize the performance of one of the most popular and versatile platforms on the market. In order to do so without a drastic increase in weight we developed the GGP365 barrel. With the interchangeability of the P365 there was no need to change any internal components. The barrel is easily installed by sliding into the frame and utilizing the adjustable barrel nut. One quick turn and the barrel is removed and replaced with the GGP365. The barrel has a 1/10 twist and is constructed of 416R Stainless Steel. The Black Nitride finish provides a durable coating while at the same time providing improved durability without hindering performance. The final dicing and cleaning of the GGP365 is performed by hand to ensure a smooth chamber and gas port without any swirl or imperfection. This barrel will fit any P365 full size non-threaded model. The GGP365 is designed to work in harmony with the factory 9mm slide/caliber combination. By changing one simple barrel component you not only improve the performance of your SIG P365; it is possible to turn a brand new pistol into a completely different platform while maintaining the same or improved functionality.image
