SIG Sauer P320 AXG Combat Custom Works 9mm, Compact, 4.6 in Threaded Barrel (1/2x28), HAO Compensator, FDE Alloy Frame, Optics-Cut Nitron Slide, 3x 21-Round Magazines
This limited-run P320 AXG Combat from SIG Custom Works pairs a compact, FDE-anodized aluminum alloy AXG grip module with a black Nitron optics-cut slide and a factory 4.6 inch threaded barrel. It arrives enhanced with a HAO-marked compensator and a thumb-shelf takedown lever, and includes three 21-round steel magazines. As a Custom Works release, it comes with the challenge coin, certificate, and lockable hard case, plus an Armory Craft recoil assembly and springs.
The AXG alloy frame provides a carry-length grip with removable SIG SAUER-logo panels, checkered frontstrap and backstrap, and an extended beavertail. The slide features front and rear cocking serrations and suppressor-height iron sights with a green-dot front and black rear, complementing the two-tone black/FDE finish. A Picatinny accessory rail is machined into the dustcover.
The extended, threaded 1/2x28 barrel supports muzzle devices and ships with a separate thread protector. The pistol is striker-fired with a flat, skeletonized trigger. The slide is cut for optics compatible with the SIG Romeo1Pro/Leupold DeltaPoint Pro footprint per factory literature, and the cover plate is removed.
Three 21-round steel magazines with extended basepads (marked "MADE IN ITALY") provide a 21+1 capacity. This U.S.-made Custom Works model includes the Certified Custom certificate and coin, the SIG Sauer manual, and a SIG Custom Works lockable hard case. Manufacturer part number: 320AXGCA-9-CW-CBT-TB-R2.
