Having a red-dot-ready slide on your SIG Sauer P365XL can only improve what is already an incredible platform for today's modern concealed-carry holder. ZEV Technologies came up with the perfect option to enhance your pistol platform with its Octane Slide, designed to accept a number of popular reflex sights. Each ZEV Technologies Octane Slide comes outfitted with a milled slot at the rear that's specifically designed to accommodate a Shield RMSc, SIG RomeoZero or Holosun HS407K. The milled slot sits just forward of the rear sight, so you can install and remove your optic without disturbing your open rear sight, and it also allows for the installation of suppressor-height sights for co-witnessing. A cover plate is included for use without an optic. The ZEV Technologies Octane Slide designed for SIG Sauer handguns also comes with the company's unique slide-channeling serrations. This offers an enhanced gripping surface and reduces glare, so you won't be distracted by sun rays reflecting off your slide surface. The slide is also treated with a black DLC or gray coating that's tough enough to withstand heavy use while preventing wear and corrosion.
