SIG Sauer P320-M17 9mm Full-Size, Optics-Ready, Coyote-Tan PVD

This full-size 9mm striker-fired pistol delivers a 21+1 capacity, striker and manual safeties, and SIGLITE night sights, giving buyers the exact feature set that earned the military contract.

What’s Included
- SIG Sauer factory hard case (gray polymer)

- 2 × 21-round steel magazines with polymer base pads
- 1 × 17-round steel magazine with polymer base pad
This P320-M17 retains the modular fire-control unit that defines the P320 family, allowing caliber or grip module swaps without an FFL transfer. The serialized stainless-steel FCU plate is visible through the window on the coyote polymer grip module.
The carbon-steel 4.7-inch barrel sits under a stainless-steel slide coated in durable coyote-tan PVD. Forward and rear cocking serrations aid manipulation, and the factory R2 cut accepts the same optics as military-issue handguns.
SIGLITE tritium night sights are standard: a bright white-ring front post plus a two-dot rear plate that can be removed when mounting an optic. The 6.6-inch sight radius makes for steady sight alignment in low light.
Controls mirror the Army specification—ambidextrous manual thumb safety, reversible magazine catch, and black-finished slide stop levers that contrast with the coyote frame. Three magazines (two 21-round, one 17-round) ship with the pistol to maximize on-board capacity.
Made in the USA, this M17 variant bears SIG Sauer part number 320F-9-M17-MS. The case label dated April 28 2020 confirms recent manufacture and authentic military-pattern configuration.
