Either I got the first SI magwell that doesn't fit right directly out of the box or these are nearly a no-go for the pf940c 76% frames. I got it installed, but I had to use a combination of strategic filing, and my body weight to get it seated correctly to accept the retention screw.
If you're using an 80% frame you're probably good to go out of the box (all of mine were), but if it's a 76% maybe explore other options unless you don't mind a little bit more fit and finish work.

Perfect fit and looks great. Would highly recommend this for the Poly80 brand lower/grip.

Have been searching for a magwell that would fit my Glock-build, was questioning what would work. I am glad to have found this magwell, works great. No regrets, would recommend for Polymer80 build.

My hand fits a glock 17 frame better than a glock 19 frame but this magwell makes the fit on a glock 19 frame perfect. Cant beat the price either. Perfect fit in the polymer 80 frame too. Ive always been a fan of anything strike industries makes.

The fitment of this is terrible. Its too easy to pull off. Looks cool but not practical. The 3d printed one I got from a no name ebay guy fits better then this. I dont what else to say but they are making write more, just dont fall for this one and get something else

I bought this product for a pf940c and will not fit. Tried to trim the part to get the back strap portion to fit. When it finally got into place. The chamfered portion of the mag well doesn’t sit flush with the frame. I’ve used multiple parts from strike industry before. This is by far the worst product Iv had experienced with.

I tried using my 15 round Glock mag and it it was extremely difficult to seat because the magwell extended past the bottom of the mag. I then tried my 15 round Pmag and it too was difficult to seat because it was pretty much flush with the magwell
