There are about a bazillion aftermarket parts and accessories available for Glock pistols. Some folks will tell you that you don’t need any of them, others will swear by product X or Y. One of the more popular Glock modifications that people make is to install a grip plug. But is this really a good idea?
What is a Grip Plug?
As you can see, grip plugs fit into the gap in the back of the frame of Glock pistols, and are designed to keep dirt and debris out of the internals of the gun. Some grip plugs also claim to provide additional benefits like adding extra weight, countering recoil, and guiding the magazine into the mag well.
Sounds like a good idea, right?
In my opinion, installing a grip plug isn’t a great idea and here’s why.
The first reason has to do with the dirt and debris argument. There are two schools of thought: the first camp will tell you that having a grip plug is a must, because it keeps dirt and debris out of the pistol. The other camp will tell you that you shouldn’t use a grip plug because Glock engineered the pistol with a gap to allow dirt and debris to fall out of the gun. I fall into the second camp. If you somehow manage to pack the grip plug full of dirt, not only will the gun still function, but the open bottom will allow the dirt to fall out of the gun.
The second reason I don’t think grip plugs are a good idea is that the gap actually allows you to get a better grip on the magazine if you ever need to clear a Type III malfunction (double feed). Sometimes it takes a good bit of force to rip the magazine out of the gun, even with the slide locked to the rear. Your thumb will fit into this gap in the frame and allow you to get a better grip on the magazine.

So what do you guys think? Grips plugs – good idea or bad idea?
