New OEM 30-Round Magazines for the Sig Sauer P320

For years we've been asking for extended magazines for the classic P-Series and P320. About 5 years ago SIG even stated that they were going to have extended magazines for their handguns. This was back when SIG was making their Adaptive Carbine Platform kits. The ACP program died off and with it went the larger magazines. Our fortunes have changes with an unexpected announcement. We are finally getting extended magazines, but for now it's only the P320. We'll take it.

SIG will soon be shipping us the first batch of 30-round 9mm magazines for the P320. The photos show both a standard floorplate and a floorplate with a overmolding that coves the front and sides. The rear appears to be exposed just like the 21-round magazines. It would appear they just stretched the 21rd mag out with a larger spring and a new follower. If the 21rd magazines are any indication you will want a speed loader to sav your fingers when you get to the final rounds. The spring tension will probably be pretty high on the last couple rounds.

Head over to our webstore to check out the magazines. If they aren't in stock you can sign up for the in-stock notification and we will email you as soon as SIG makes the next delivery.
