This is the factory mag for your full-size P320 or P250 when you want solid capacity without going extended. Sig built this 17-rounder to their exact specifications with a heat-treated steel body, high-strength steel spring, and polymer follower that work together to feed rounds flawlessly every single time you need them. The black steel tube paired with the coyote baseplate looks right at home on any coyote-finished P320, and the side witness holes let you see how many rounds you're carrying at a glance.
The construction here is straightforward and durable. You get a double-stack mag that holds every bit of its 17-round capacity right out of the box with no break-in period required. The polymer basepad takes the abuse when you reload or drop it, and the reinforced feed lips work with the heavy-duty spring to push rounds up reliably. This is a standard-capacity choice for range days, training, or duty carry depending on your setup.
Compatibility is straightforward: full-size P320 pistols, P250 full-size, and the M17/M18 military platform all run this mag without modification. The 17-round capacity sits between the 10-round standard and the 21-round extended options, giving you mid-range capacity when you want it. If you run a P320 Carry with the full-size grip module, these work perfectly too.
Yes, this magazine is fully compatible with P250 full-size pistols. It also works in P320 full-size, P320 Carry, and the M17/M18 platforms. The full-size platform magazines are interchangeable across these models.
The 17-round mag is standard capacity and sits flush or nearly flush with the grip, while the 21-round extended mag adds about an inch of length below the magwell for higher capacity. Pick the 17-round if you want baseline capacity, or go with the 21-rounder if you want extra rounds and don't mind the slight extension.
No. These factory mags will hold and feed 17 rounds reliably right out of the box. The spring and follower are ready to work, so there's no need to pre-load and let them sit before using them.
They are. The side witness holes let you see the witness rings on the follower, so you can count loaded rounds without dumping the mag. It's a quick way to verify your round count during training or reloading.
