Part of SIG Sauer’s Reserve Collection limited-run program for 2024, this Custom Works P226-XFIVE pairs a stainless steel slide and frame with a high-polish black DLC finish. The slide incorporates an expansion-chamber compensator with upward ports and front and rear cocking serrations, and it includes an optics-ready cut.
The single-action-only system features an ambidextrous manual safety and no decocking lever. A flat-faced trigger is user-adjustable for reach, pull weight, and overtravel. Control enhancements include an extended slide stop and a sport-style takedown lever shelf, while the extended beavertail and flared mag well aid grip and reloads.
Grip and sighting elements are competition-focused: black GridLOK metal grips with a palm swell, suppressor-height front sight, and an adjustable rear-sight plate assembly provided in the case. A SIG Sauer ROMEO3 MAX red dot is installed, and the sight radius is 6.8 in.
The full-size 9mm configuration uses a 4.4 in barrel, 20+1 capacity, and an unloaded weight of 48.1 oz. Dimensions are 8.6 in L x 1.7 in W x 6.0 in H. An M1913 Picatinny rail on the dustcover supports accessory mounting. This model is identified as mfg part number/SKU 226X5-9-CW-RES and is made in the USA.
