Killer Innovations Velocity Defense V1 Slide for SIG P365 XL | MDC Gray

Killer Innovations Velocity Defense V1 Slide for SIG P365 XL | MDC Gray

The Killer Innovations Velocity Defense V1 Slide for SIG P365 XL transforms the P365 platform with aggressive machining, enhanced slide control, and broad micro red dot compatibility. Machined from high-quality 17-4 stainless steel and protected by a durable Grey PVD coating, this XL-length slide is designed for SIG P365XL, P365 XMacro, and P365 Spectre configurations using a 3.7-inch barrel.

Killer Innovations incorporates its Enhanced Grip Feature, or E.G.F. Cuts, into the Velocity Defense V1 to provide secure manipulation surfaces along the slide. The pronounced machining gives the shooter positive purchase when charging the pistol, performing a chamber check, or clearing the action while also creating the distinctive styling of the Velocity Defense series.

A dual-cut optic pattern greatly expands red dot options beyond a single proprietary footprint. The slide supports the Trijicon RMRcc as well as popular micro optics including the Holosun EPS Carry, Holosun 407K/507K, SIG Sauer RomeoZero and RomeoZero Elite, Shield RMSc-family optics, and Swampfox Sentinel. A Micro Optic Shim and RMRcc bushings are included to support the applicable mounting configurations.

The MDC Gray version uses Killer Innovations’ Grey PVD coating for a durable exterior designed to withstand demanding use while maintaining a refined, neutral appearance. At approximately 7.45 ounces, the XL slide combines robust stainless-steel construction with extensive precision machining for a premium P365 upper build.
