FDEZ Comp'd P365 XXL 2.0 Slide, with Optic Mount & Cover

Usually ships in 1-2 business days unless Cerakote is added

Intergrally Compensated P365 XXL slides are designed to be used with a P365 XL length barrel (3.7") and a P365XL recoil spring assembly.


Slide come in a high quality QPQ Black Nitride finish. QPQ is a double black nitride finish with a polish between each black nitride quench. This provides a very high quality finish that is extremely durable and resistant to correosion.



The single port XXL and dual port XL slides offer a very similar performance as the large single port and expansion chamber maximizes performance of the smaller comp. 


These slides will fit XL holsters with open ends, although due to variations in holsters we recommend an adjustable retention holster.


the 2.0 is our XXL slide redesigned to be the ultimate EDC option. These slides feature less cosmetic openings to reduce the possibility of dust and debris from entering into the firearm, while still allowing for the use of our ported barrels. They also have wider serrations that allow for your fingers to sink in and really grab hold of the slide. Overall the 2.0 slide has a unique new look and is sure to stand out for both its looks and its performance.
