If I'm not mistaken...
If enough dirt and grime can get up there it can seize the works.
I see lots of ads for 'Plugs' for Glock handles. How come Glocks even have holes that need to be plugged?
I believe the primary function of the tiny hole at the top of the much-larger lower grip cavity is to allow water to quickly drain out of the pistol if it is completely immersed. The fact that the same hole may allow a small amount dirt into the weapon is not a problem for the vast majority of users, as the pistol is cleaned periodically before this small amount could build-up enough to cause any problems. The weapon has passed many military dirt/dust tests, and if the hole was a problem, you'd have solid evidence of it by now.
I've carried my Glocks outside quite a bit in forever-windy North Dakota, and dirt/dust/crud/snow/ice build-up has never been a problem, even when I shoot them a lot and clean semi-annually. I have plugs in some of my Glocks, and not in others. For me, it's not a big deal either way.
I've also cleaned a few abused-by-the-former-owner Glocks, and despite some of them being absolutely filthy with firing residue, none of then had any grip cavity crud build-up problems, either. It's a total non-issue, in my opinion.
What if I say its there to allow a weighted base plate to be screwed on allowing persons to better manage the recoil on larger calibres. I think I read this somewhere.
I am hoping we are referring to the same hole here.....lol
I have one in mine because I like the looks of it and to keep me from worrying about anything finding it's way down in my gun.
Yep. I have it for looks. Makes the weapon seem more complete.
Gaston designed it with a hole in the bottom, it stays that way for me... just my opinion
Plugs can keep stuff out, but they could also keep stuff in. I refuse to plug the butt of my Glock.
I've only been on this forum for about 8 or 9 months and I think I've seen this same topic appear as a new thread about 5 times -- and the post content is always the same. Maybe this should be a "sticky".
I use one on my 30. It adds a little more comfort to the grip for me. I take it out and use compressed air occasionally when cleaning to blow out any debris. Before I bought it, I did notice small amounts of "carry" dust and lint in the cavity, but probably not enough to worry about.
Between the plug and finger-grip extensions om the mags, it adds a lot more comfort to the grip for me.
Where it is legal you insert the attachment for the Glock shoulder stock in that hole. (Even where it is illegal you would attach the shoulder stock by inserting the arm into that hole.)
Solution: Drink an entire bottle of white, red, or rose wine. Save the cork. After you sober up carve the cork to fit the opening. Press it in. Remember the good time you had drinking the wine. The plug is free. (Or buy the shoulder stock).
I don't know for sure, but Glock probably put the hollow space there for weight reduction. Besides, it does catch a lot of dust bunnies and ghost turds up in there.
