(5 out of 5) Bigger capacity = more rounds downrange!!!!!
by from Elkins Park, PA on

Since 9mm ammo is pretty cheap and reliable, I needed an extra magazine that holds more rounds aka bigger capacity, and this is the perfect one for my Sig Sauer P320 when loaded with self-defense rounds, which im saving for emergency situations at home. In fact, im also making plans on buying another one to test at the shooting range during a future visit, so hats off to SportsmansOutdoorSuperstore for carrying an excellent product!!!!!

(5 out of 5) Great product at great price
by from OKEANA, OH on

These magazines are hard to find right now during the pandemic. They are even harder to find at a price any less than msrp. Thankful for a company that doesnt take advantage of its customers when most others are. Well done Sportsmans Outdoor Superstore!

(5 out of 5) Finest kind.
by from Bolingbrook, IL on

As stated, this is an OEM magazine. It fits & performs flawlessly in the P320. The 4 extra rounds, over the 17 round mag, makes this a great spare mag!

(5 out of 5) Superb
by from Columbus, OH on

Product is just as pictured newer model magazine. I have yet to test it, but I’m assuming it will perform well. I was disappointed to see that it would’ve taken longer than expected, but arrived in just a few days! Will definitely come back for another. Thank you guys!!!

(5 out of 5) Great product for a great price!
by from Sunrise, FL on

These are $49 new directly from Sig. I got these for $36 each here. Great deal for great mags.

(5 out of 5) Got ammo
by from Conway, AR on

What can I say 21 rounds on 9mm for my p320 looks great but also work great, and who does not need 21 rounds of 9mm......?? ??????

I have 3 of these that I use in my Sig P320 9mm Compact and they work great, fully loaded. I use an X-Grip to cover the gap.
