Glock 23 Are Grip Plugs a Good Idea?

    There is. It's because of how injection molding works.

    Without getting too deep in the weeds, the tool that makes the Glock frame is a big piece of steel cut in half. Each half of the tool forms 1/2 of the frame. You can see what are called parting lines all along the frame from front to back. That is where the 2 pieces of steel come together when the mold is closed.

    One of the principles of injection molding is that you want the thickness of the part to be fairly consistent so the plastic flows well, and fills the cavity completely. If a section changes thickness drastically, the plastic behaves oddly during the fill cycle and may give all manner of defects and sections of the tool that are not filled.

    This is one of the reasons they don't just fill the void with plastic. The other reason is it would take hours to cool, and as it cooled it would warp the entire part as the polymer shrinks and the part reaches design size.

    In order to form the closed section of the magwell, a piece of steel called a slide goes in there as the tool closes, and is removed before the tool is opened. Otherwise the part would lock the tool (you could not open it without destroying the part).

    Ergonomics says the length of the grip (front front to back) needs to be X, and the space needed for the magazine is less than that, so you end up with a space that needs filling somehow. The plug is a typical solution. Another solution would be to make the magazines bigger to take up the space but that has it's own tails I'm sure. I hate the unfinished look of the frame so I use them. They seem to have no negative on function, so it's just an option for those that want it.

    I hear that Von Hayse uses those to keep his stash from falling out.

    I read somewhere that the frame is made to flex and this is one of the reasons for the opening. It helps absorb recoil. Looks kinda weird but I figure Glock knows what they are doing

    I've seen some shooters report that debris will get hung up in the void if plugged.
    Maybe powder kernels, brass chips or whatever can get in there ?

    I don't shoot my Glocks enough to worry about it.

    Well in case your magazine gets stuck in the glock that opening is to get your thumb in there and get a grip on it to pull the magazine out. We were taught that in one of out Defensive carry classes several years ago. It's up to you if you want to use a butt plug!

    I have two Glocks that came with them, they must be glued in and I am not going to pry them out so in they stay.

    I took my first Glock to a USPSA meet and during a stage managed to jam the top round in the magazine in that hole in a botched reload. Felt like it took ten minutes to get it out. I’ve had “butt plugs” in every Glock I have ever since. Either the Pearce or the Seattle Slug. The slug can indeed lead to a crack in the frame.

    I thought that little hole was where you stashed your weed.

    They help a lot with standing reloads. I don't think keeping stuff in or out of the frame makes much difference either way.

    wouldn't be the first time someone stashed their dope in their butt.

    Dude please keep your junk away from your Glock, it's just unsettling to visualize what you're suggesting. We all love our Glocks, but there are limits to the degree of our affection.

    To be fair, he didn't say his junk... he might have a large group of amorous men trying to "have their way" with his gun, and uses the plug to deter them. Like a chastity belt, so to speak.

    :laughing:

    The pistol comes with a magwell.
    It's that void inside the grip where the mags go.

    ;)
