Description

This 3.7" slide assembly is finished in Matte Black DLC and fits all P365 9mm grip module sizes. The 3.7" slide length provides an extended slide look for P365, P365-X, and P365-XL models, while offering a flush-fit look on P365-XMACRO size grip modules, such as the AXG, AXG LEGION, and FUSE.This slide features the new SIG-LOC (Leverage Optimized Connection) Compact footprint, providing the industry's strongest, most rigid interface between your optic and pistol slide. Only available on SIG SAUER slides, SIG-LOC establishes five points of contact between the slide and optic to eliminate a shift in zero created by extensive shock from recoil and harsh impacts.This is a complete slide assembly, including all internal slide parts, and front and rear XRAY3 Day/Night sights. 3.7" Barrel and recoil spring assemblies are sold separately.Features:- SIG-LOC Optic ready, capable of mounting both SIG-LOC Compact and Shield RMS-C footprints.- XRAY3 Day/Night sights.- Removable flush-fit optics plate with top accessible screws.- Matte Black DLC.For use with:-Standard 9MM, 3.7" non-threaded barrelsCompatible with all 9mm P365X, P365-XL, P365-XMACRO and P365-AXG grip modules.Optic not includedLearn more about SIG-LOC(TM)
