Pachmayr 03889 Grip Extender, Sig Sauer P320 Sub-Compact (Black)

Based on the reviews, there seems to be some confusion about what version of the P320 these can be use with. Hopefully this review can clear that up. First, these are designed for the P320 SUBcompact, not the P320 compact. The P320 subcompact is a now discontinued version of the gun with a 3.5 inch barrel that holds 12+1 9mm in a flush fit magazine. Second, these extensions will only fit your magazines if they have a circular hole in the base plate rather than a rectangular hole. My 12 round magazine (PICTURED RIGHT) has a circular hole. My 15 (PICTURED LEFT),17 and 21 round magazines have a rectangular hole.All that out of the way, installation was a piece of cake. Literally took 3 minutes to unload the mag, swap the baseplate, and reload it. I have large hands and this extended baseplate gives my pinky finger something to hold onto with the 12 round magazine. If you own a P320 subcompact this upgrade is a no brainer for the price.

Based on the reviews I've seen and the stock photos, I was not 100% sold on these.. but for the price, I took a chance. I have to say that I was pleasantly surprised. Are they exactly like the factory stock extensions that come on the P320 subcompact? No, not quite as good.. but they add a nice extra lip at the base that aids pinky retention. There are some gaps between the extension at the bottom of the grip and base pad, but could not feel any pinching. If you want perfect, buy the factory mags that come with the extension built in. For < 10 bucks a pair for these, a no brainer and definitely recommended.

this did not fit not even a little. I tried a bunch of times and thought maybe it was just me. then I took it to a gun shop and they said it wouldn’t fit either. unfortunately not was a no go.

I really like these. They allow the subcompact 12 round mag to have a fuller, more comfortable grip and still conceal better than using a larger 15 round mag with an adapter. Just take a minute to sand or file the edges. I really didn't bother to do that until I did feel the sharp edge against bare skin. But it is so easy to round that edge that it's not really an issue. If you can load a magazine you can sand an edge. To install, just push the center button to remove the old base pad and slide it off, while you hold the spring. Then after seeing the groove that slides onto the magazine body, slide the new on until the pin snaps into the new basepad. It may take a try or two, but it's not that hard to do.

I absolutely love this...I bought the "x-grip" so I can have a bigger magazine, and more hand room, but didn't like it.It keeps the gun small as it is designed to be, but with that little extra room for your thumb.Some reviews talk about the roughness of the base, but I don't mind it, it kind of matches with the grip.When you first try putting the base on your magazine, it'll be a little tough to get on, but will fit.I wish they would offer more color options. I'll be sanding one down and paint it myself, lol. Hopefully I won't mess it up.

Kind of weird to install but they fit and work well for your pinky on the subcompact magazine. These ONLY fit the 12 round subcompact magazine.this mag has ears that turn in at the bottom unlike most sig mags. If you can't get it on the mag - try it once with the spring removed so you can tell the angle and then try it again with the spring back in.

Shorted 1 extension.

It was fairly easy to install. Product is tight fitting (which is a good thing), i removed my magazine plate then spring so i could see how to exactly put it on without fighting the spring you will be holding down with your finger during install. I reinstalled the spring and installed the extension. Feels great when holding and shooting. I bought two since the price was great without noticing there are two extensions in each package. So now i feel like i got a even better deal.
