Description
That hollow void at the heel of your Glock Gen4 grip does two things nobody loves: it collects grit and it leaves the balance feeling a touch top-heavy. The Rival Arms Grip Plug takes care of both. It drops into the cavity for a clean, flush look and a snug, rattle-free fit that stays put once it's seated. No gunsmithing, no fuss, just a quick install and you're back on the range.
What the Rival Arms Grip Plug Does for Your Glock
Beyond keeping dirt and lint out of the frame, the extra mass in the lower portion of the grip shifts the balance point down and back a bit. That subtle change helps settle muzzle rise and trims felt recoil, so your sights come back on target quicker between shots. It's the kind of small upgrade you notice most during rapid strings, where faster follow-ups and a more consistent feel add up.
Built From Machined Aluminum and Anodized
Rival Arms cuts this plug from solid aluminum on CNC equipment, then finishes it in a hard black anodize. That coating gives it a durable, corrosion-resistant surface that holds up to solvents, field conditions, and everyday handling without flaking or fading. Rival Arms builds and machines their parts in the USA and backs them with a solid warranty, so you're getting a piece that's made to last.
Fit Notes for the Gen4 Grip Plug
This one is cut for Gen4 frames and works across the popular models like the G17 and G19. It is not made for the Glock 36, 42, or 43, so if you're running one of those, this isn't the plug for you. For most double-stack Gen4 owners, though, it's a cheap, sharp-looking way to finish off the grip and clean up how the pistol handles.

Frequently Asked Questions
Which Glock models does this Gen4 grip plug fit?
It's designed for Gen4 frames and fits the common double-stack models like the G17 and G19. It is not compatible with the Glock 36, 42, or 43. If you're running a Gen3 or Gen5 pistol, Rival Arms makes separate plugs cut specifically for those frames.
Do I need any tools or gunsmithing to install the grip plug?
No tools or gunsmith required. The plug seats into the cavity at the heel of the grip for a snug, flush fit and installs in a minute or two. Once it's in place, it stays locked without rattling.
Does the grip plug really reduce recoil?
The extra aluminum adds mass to the lower part of the frame, which shifts the balance down and back and helps settle muzzle rise. The effect is subtle in the hand but tends to show up during rapid fire with quicker, more consistent follow-up shots. Think of it as a refinement to how the pistol handles rather than a dramatic change.
Will the black anodized finish hold up to cleaning and range use?
Yes. The hard black anodize is corrosion-resistant and stands up to solvents, field conditions, and regular handling without flaking or fading. It's a durable surface built for daily carry and range work alike.
