Strike Industries P320Magholder Mag Holder Polymer Compatible W/ All Sig Sa

The Strike Industries P320 magazine holder is a polymer-built spare mag carrier purpose-built for SIG SAUER P320 pistols and grip modules. If you run a P320 for duty, competition, or serious sport shooting, keeping a reload within immediate reach transforms your speed and confidence on the move. This holder mounts directly to Picatinny rail slots on most P320 grip modules, angling your spare magazine forward at 5° for intuitive access under stress.

The magic is in the execution. Strike Industries engineered this mag holder with positive locking retention—your round stays secure during movement, drawstrokes, and the inevitable bumps of hard use—yet releases cleanly when you need it. The pre-installed SI Modular Magazine Release handles the job ambidextrous and can be configured for left or right hand operation. For shooters who prefer a different button profile, an extended button is included in the box so you can dial in what works for your grip and technique.

Installation is straightforward: the holder bolts to any P320 grip module equipped with a 1913 Picatinny rail, and Strike includes all the hardware you need—set screws, a nut, Loctite threadlocker, and a Torx tool—to get it mounted solid the first time. The polymer construction keeps weight minimal while standing up to daily carry, training rounds, and outdoor conditions. Whether you're building a duty rig, setting up for the range, or configuring an emergency backup, this is a no-fuss, no-compromise way to carry a spare mag on your P320.
