Mag Sig P320 9mm 21rd M17 Coyote

The Mag Sig P320 9mm 21rd M17 Coyote is the standard-issue extended magazine for the U.S. military’s modular handgun system. Designed to meet rigorous performance standards, this factory magazine offers a significant capacity advantage over standard flush-fit options while maintaining the structural integrity required for combat and law enforcement duty. When reliability is non-negotiable, utilizing OEM components ensures that internal geometries align perfectly with the P320’s feed ramp and locking mechanism.

Constructed from premium carbon steel with a friction-reducing finish, this 21-round magazine facilitates smooth insertion and extraction from the magwell. The coyote tan polymer baseplate is specifically designed to match the M17 and M18 aesthetics while providing extra surface area for a positive grip during high-stress reloads. This extended floorplate also serves as a protective buffer, absorbing impact during tactical reloads on hard surfaces like concrete or gravel, ensuring the magazine remains functional throughout its service life.

Internally, the Mag Sig P320 9mm 21rd M17 Coyote utilizes a high-tensile steel spring and a low-friction follower. These specifications are critical for maintaining consistent upward pressure on the cartridge stack, preventing nose-dives or failures to feed even when the magazine is loaded to its full capacity. This magazine is compatible with all full-size P320 and M17 grip modules, as well as carry-sized modules, making it a versatile choice for duty use, competitive shooting, or home defense.

Professional operators understand that the magazine is often the weakest link in any semi-automatic system. By selecting the Mag Sig P320 9mm 21rd M17 Coyote, users are investing in a component tested to the same standards as the firearm itself. Whether you are looking for a spare for your duty belt or seeking additional rounds for a range session, this magazine provides the unflinching reliability and accuracy that SIG SAUER is known for worldwide.
