WILSON EXTENDED SLIDE RELEASE WCP320

Description

The factory slide release on the Sig P320 is deliberately low-profile — a reasonable choice for a duty pistol that needs to resist accidental actuation, but one that can slow down a deliberate reload under pressure. Wilson Combat’s extended slide release is a direct replacement designed to close that gap. It sits 0.04 inches wider than the factory part, which is enough to give smaller or average-sized hands a more positive purchase on the lever without requiring an awkward shift in grip. The geometry keeps the release reachable without placing it where a thumbs-forward grip will inadvertently drop the slide.

The part is ambidextrous, so it works equally for left- and right-handed shooters without modification. Construction is precision-stamped ordnance steel rather than cast or MIM, which keeps the lever stiff and dimensionally consistent under repeated cycling. The black nitride surface treatment goes into the steel rather than sitting on top of it, providing corrosion resistance and a hard wear surface that holds up through extended range use and holster draw cycles. Fit is drop-in for all WCP320 and P320 models chambered in 9mm, .357 Sig, and .40 S&W — no fitting, stoning, or gunsmithing required.

This is a straightforward upgrade for any P320 shooter who has found themselves fumbling the stock release during timed drills or under stress. Wilson Combat manufactures it to the same standards as their other P320 components, and the part number 320-SR fits the existing fire control unit without alteration.
