Killer Innovations Velocity Defense V1 Slide for SIG P365 XL | DLC Black

Killer Innovations Velocity Defense V1 Slide for SIG P365 XL | DLC Black

The Killer Innovations Velocity Defense V1 Slide for SIG P365 XL in DLC Black is a full-length optics-ready slide designed for P365XL, P365 XMacro, and P365 Spectre configurations using a 3.7-inch barrel. Compared with the shorter Standard model, the XL slide provides additional slide length and mass while retaining the same aggressive Velocity V1 styling, dual optic system, and durable 17-4 stainless steel construction.

Measuring approximately 3.67 inches overall and weighing 7.45 ounces, the XL V1 slide is built around the longer P365 upper architecture. This makes it the correct choice for builders working with P365XL-length barrels and slide assemblies rather than standard 3.1-inch P365 components.

Killer Innovations incorporates its Enhanced Grip Feature cuts throughout the slide to provide additional gripping surfaces for manipulation. The DLC Black coating gives the 17-4 stainless body a durable, subdued finish that works well in all-black builds or with contrasting barrels and grip modules.

The dual-cut optic pattern supports a broad range of micro red dots, including the Trijicon RMRcc, Holosun EPS Carry, Holosun 507K, Shield RMSc-family optics, SIG Sauer ROMEOZero, and Swampfox Sentinel. A micro optic shim and RMRcc bushings are included to simplify setup across the supported mounting patterns.

XL-Length P365 Slide

The XL model is designed specifically around the longer 3.7-inch P365 barrel system. Its 3.67-inch slide length makes it the appropriate Velocity V1 option for P365XL, XMacro, and Spectre builds where the longer upper configuration is required.

Optics-Ready Velocity V1 Design

The dual-cut optic system gives the XL slide broad micro-red-dot compatibility without locking the build into a single footprint. This allows the slide to support several of the most common carry-optic options used across the P365XL and XMacro platforms.
