NDZ Performance Jentra JP7 Grip Frame Insert Plug for Glock Gen 4 20, 21, 40, 41 in 10mm & .45, Black Polymer - Plain

Great product don’t know why Glock doesn’t include this but NDZ has a perfect fit especially value for the money.

It’s an expensive little piece of plastic that I suspect cost about .5 cents to manufacture, but the fit is 100% spot on, and it fills that gap perfectly on my Glock 21 Gen-4. The packaging it came in probably cost NDZ more to acquire than the piece itself. As other reviews have indicated, if you want to use this part, you cannot use the grip extensions in conjunction with it. I don’t use them to begin with, so this plug works for me. The installation took about three seconds. Easy.

Perfect fit to fill the gap. The only drawback is when you install this, you can no longer use the grip overlays. Will not allow them to mount flush.

This is the second plug I’ve purchased for my Glocks - a 17 and this one for a Glock 20 Gen 4. It does two things really well: It adds a FINISHED look to the gun, but more importantly, it makes reloads smoother by filling in the cutout at the back of the magazine well that can catch on the mag when inserted. And if you’re worried about not being able to get a grip on the magazine to strip it out of the gun if stuck, I find there’s still enough room for me to get the end of my thumb between the back of the mag and the plug to remove the mag if need be. All in all, this product is a no-brainer. Good looking, super simple install, and purposeful.

4 stars only because of cost. Fits perfectly in Glock 21 Gen4. Looks good

Excelente artículo al colocarlo se ve muy bien

As advertised, it’s a Glock grip plug.

It fit my G20 like perfectly. Solidly in place. So happy to finally see that gaping hole plugged. Thank you for this very simple, but very much needed tiny piece of plastic.

Fit perfectly
