I bought this for my 320 sub thinking it would fit against the frame as visually it matches up very well. It looked as if I had purchased the correct piece. And I did just for the compact. Its a little loose on the magazine itself but it does secure very well on the 320 compact. Even on the sub it gives my pinky a resting place I very much appreciate. The back is molded to git with the regular compact and will need some modifications to fit the sub well. I likely read through the part modification too quickly in my research as the floating pinky was making me nuts. But I would buy it again and my only real complaint was how it fit the magazine itself. To me it was not snug enough and its the same mag that would go in any of the 320 series pistols.

The idea of using a well-designed spacer to fill in the gap with an extended 17 round mag on your P320 compact is perfect except that there is no method to lock it in place. The material is a soft and pretty flexible and offers no way to "clip-it" in place. This becomes a real issue when you have two of these in your magazine pouch bouncing around. I train often at Sig Sauer Academy and found myself constantly fidgeting with them to make sure they are in the correct position. When doing fast mag changes during drills it can slow you down if they have shifted hence the always checking they are positioned properly. Love the idea not liking the implementation.

fits well just dont like the fact that it is always loose need to design it with some sort of locking tab also need to make 1 to work in the compact model with the 21 round mag

Great product! Changes my whole gun feels perfect now. But was expecting it to be hard polymer not soft rubber. Overall I love it. My hands used to go off the edge of the compact but now it's perfect.

First off, the seller got it to me super quick! I had read various reviews where folks were complaining about how it slips around on the mag. This is true, but it is a simple fix. I simply glued it in place with Gorilla Glue and wiped away the excess. It works as designed and stays in place. I run my Sig P320 Compact nine with the 17 rounder and x-grip adapter in place. That gives me a total of eighteen rounds in the gun counting the chambered cartridge. That's a lot of peace of mind and the x-grip product allows for additional real estate on the weapon for good purchase and is an attractive addition to the pistol itself. I think x-grip hit a home run with this simple but very effective product.
