Q & A
Is this just a barrel and recoil spring swap for a 9mm P365?
No. This is a complete, factory-produced slide assembly engineered specifically for the .380 ACP cartridge. It is designed as a dedicated system for reliability and is not a simple parts conversion.
Will this work with my existing P365 grip module and magazine?
This slide assembly will drop directly onto your existing P365 Fire Control Unit (FCU). However, you must use P365-380 specific magazines, as the 9mm magazines are not compatible due to feed lip geometry.
What is included with the purchase?
You receive the complete, serialized slide assembly. This includes the LUXE-finished slide, barrel, recoil spring assembly, and Siglite® night sights. It does not include a grip module, FCU, or magazine.
