Description
The Rival Arms RA10P302A gives your P320 Carry a serious upgrade with a precision-machined slide that handles the optic mounting duties right out of the box. Built from 416 stainless steel and finished with a QPQ thermo-chemical coating, this slide resists corrosion and normal wear without any fuss. If you're moving from iron sights to a red dot or building a fresh carry gun, this is a solid foundation.
What makes this slide stand out is the attention to detail in the machining. The recessed cuts accommodate Docter and RMR-style optics, so you have flexibility in which red dot you run. The front and rear serrations give you reliable grip points for manipulating the slide, whether you're charging it fresh or working the action under stress. The window cuts milled into the slide do double duty: they help keep things cool during extended range sessions and cut some weight without compromising structure.
Built for precision, finished for reliability
Rival Arms machines every one of these slides from a billet, which means tighter tolerances and better overall consistency than investment casting alternatives. The QPQ finish isn't just about looks either. It hardens the steel surface and creates a barrier against moisture and daily wear. You get a slide that'll hold its function and appearance through years of carry and training.
Docter and RMR compatible mounting
The optic cuts are milled to accept both Docter and RMR-style red dots, giving you options when it comes time to choose your sight. This flexibility means you're not locked into one brand or footprint. Once you drop it on your P320 Carry frame, it's ready to accept your optic of choice with proper mounting hardware.

Frequently Asked Questions
What red dot optics work with this RA10P302A slide?
The RA10P302A is cut for Docter and Noblex style optics. It's also compatible with RMR-style optics through the same mounting footprint. Many shooters run Holosun, Vortex, and Burris red dots on this cut pattern as well. Check your optic manufacturer specs to confirm compatibility with the Docter cut footprint.
Is this a stripped slide or does it come with internals?
This is a stripped slide housing only. You'll need to install the barrel, recoil spring, and complete the slide internals. Rival Arms offers a slide completion kit separately that includes the firing pin, extractor, springs, and other internal components needed to finish your build.
Can I use this RA10P302A slide on any P320 frame?
This slide is specifically sized and machined for the P320 Carry model. It's not compatible with P320 Full Size, Compact, or X-Series frames due to different slide dimensions. Make sure you're pairing it with a P320 Carry fire control unit.
Does the QPQ finish require maintenance?
The QPQ thermo-chemical finish is fairly low maintenance. It resists corrosion and daily wear without special care. Standard firearm maintenance like keeping it clean and lightly oiled is all you need. The finish holds up well to regular carry and training use.
