Pearce GripPG-G4MF Frame Insert for Mid and Full Size Glock Gen 4 Frames (NOT for 10mm or .45ACP) Black

Fits Glock 31 just fine. Keeps dust out of the frame.

I installed these on both a G17.5 and a G22.4. I have big hands so I use the large size OEM backstraps. Many of the other brands of plugs aren't compatible with backstraps, but these installed easily and clean up the look of the gun.

Works like a champ in my Gen 4 Glock 22. I just had to remove my back strap first in order to push this plug in and reinstall my back strap. So easy, a caveman could do it.

Worked great and fit was spot on.

Fit great. Plugged the hole, looks much better

I can’t offer much in the way of a review, because this thing is so simple and easy to use....I can say that it fit my Gen4 G22 perfectly. No issues with getting it installed, and it looks nice. It locks into place using the “lanyard” hole on the back of a Glock Gen 4 grip.Included photos of what it looks like installed both with and without a Glock magazine.*******************************I rely heavily on reviews when I make purchases so I put some time into reviewing everything I buy on Amazon for personal or business use so I can help other people considering that item.

These are a MUST have if you own a Glock. They snap right in the frame insert and keep dust & debris out of the frame. They also provide for a cleaner looking profile and are easy to install / remove.

It fits perfectly in my Glock 40 Gen 4 10 mm auto. I just hated the hole underneath the glock handle. Thank you for the grip plug .

Great price and great fit! This fills the gap nicely on the but of the Glock. Great product, snaps right into place.

Perfect, as advertised. Fits the Gen 4 22 perfectly, and it is made of the same material and texture as the OEM Glock stock. Looks like a natural piece of the firearm- no difference in colour either.

Perfect fit for Gen 4 G17. Never did like that gap....

Put this on a Glock 17 gen 4 bb gun and threw the backstraps on. Went in in seconds. Perfect fit. Thank You for a great product.

Inexpensive grip plug that does the job well. Doesn't really look as much like the picture as the bottom of the plug is a little more recessed appearing whereas the listed picture looks more bulky/full appearing, but not a big deal.
