Accessories for Sig P320

The SIG P320 is a modular striker-fired pistol with a serialised chassis that can move between different frame and slide sizes. Adopted by the US military as the M17 and M18, it is used in IPSC Production, Standard, and Open divisions, with the optics-ready configuration standard across the current production line.

Upgrades for the Sig P320

The Sig P320 can be tailored across the main competition upgrade areas:

• Grips – panel texture and frame profile change how consistently your hand returns to the gun, the foundation of recoil control and a repeatable draw.
• Triggers – a refined trigger sharpens the break and shortens the reset, so shots break where you expect and you are back on the sights sooner.
• Sights and red dot mounts – upgraded irons or a slide-mounted optic give a single focal plane and faster acquisition from the holster and between targets.
• Magwells – a wider, chamfered magazine well makes the reload more forgiving under stage pressure.
• Base pads – extended pads add capacity and a little weight at the base of the magazine, and help it seat reliably.
• Frame mounts and weights – added forward weight settles the muzzle and improves balance, particularly in Open setups.
• Magazine releases and thumb rests – an extended release speeds mag changes without breaking your grip, and a thumb rest gives a fixed hand reference.

Compatibility is specific to each model — confirm the fit on the individual product page before ordering.
