Frequently Asked Questions
Will this kit work with my existing P365 FCU?
Yes. This kit is designed specifically to work with your existing P365 Fire Control Unit (FCU). Simply transfer your FCU, barrel, and recoil spring assembly into the new XMACRO slide and grip module.
Is the slide coating durable?
Our staff has noted the Nitron finish is tougher than it looks. One sample in our shop has held up through multiple cleaning cycles with Hoppes No. 9 solvent without any noticeable wear or degradation.
Does this kit include an optic?
No. This kit includes the optics-ready slide with a removable plate, but the red dot optic itself is sold separately. The slide is cut for the common RMSc footprint used by sights like the SIG RomeoZero and Shield RMSc.
