"Does what it's supposed to do. The sandblasted silver finish looks fine. The pin that came with it fits very snug. I would recommend having an actual punch and mallet for install.

This goes for all mag well extensions, but you will see negative reviews saying they don't fit because they are too tight. Don't listen to the reviews written by impatient 15 year olds. If you need to drive to the store to get the right tools or some sand paper, so be it. Don't break your gun just because you're only using jerry-rigged tools.

Virtually all of these require fitment. That's how you get them as tight as possible. This one is no different.

It fit too tight initially, so I tried a rubber mallet. That didn't work either. I noted where the mag well was getting caught. I used 220 grit around the edge of the hi capa grip and continued trying to fit it until it fit (but was still very tight and required the mallet.) Then I took it back off and used some 2000 grit on the grip just so it wouldn't look terrible if I ever took off the magwell. Then I put the magwell back on. I thought about using super glue to help secure it, but I don't think it's necessary at all if you get a tight enough fit. Then I just punched the pin in.

After it was all fitted, I used a soldering Iron and 2000 grit sandpaper to match the grading of the pistol grip's magwell (so there's no lip on the inside throughout the magazine well to the extension).
