SKU: 320 Pinky Category:


An improvement over the polymer OEM base pad, our P320 Subcompact base pads are machined out of 6061 aluminum. They are much more tolerant of being dropped on rocky or cement surfaces for heavy tactical or training use. The added weight of these base pads also aids the magazine in dropping free from the magazine tunnel for rapid and consistent reloads. The extended magazine gives the shooter a more robust grip. Great for big hands or those shooters wanting a full grip for their Subcompact Sig Sauer P320.

    Just received my pinky mag extensions yesterday. Very pleased. They fit perfectly. Easy to install and best of all, they are the perfect length to allow my pinky to grip the weapon without causing a larger imprint in the carry positoipn. An elegant solution to a vexing problem. Highly recommend these quality made mag extensions!

    FAR and away the best available product I have come across to fill this need. Allows for a much more secure grip on the weapon without meaningfully increasing the footprint while carrying concealed. Super easy to install (did three mags in less then 5mins) and the subtle texture to the aluminum provides a great grip, really makes it feel like the larger compact-sized version when firing. Just a great product that I’ll definitely be recommending to other P320 SC carriers.

    Exactly the right amount of extra grip. Doesn’t add extra bulk or print more when carrying concealed. And it adds just enough extra weight on the mag, that they “jump” out of the gun when you hit the mag release. I put them on all my sc mags.
