Glock Backstrap Channel Insert

[Kraviwannabe]

For those fellow Glock owners, Glockmeister is marketing a "backstrap channel insert" which drops into that space at the bottom of your grip. It has a nice angled surface toward the mag well to help guide the mags. It also fills that stupid gap so it won't collect lint and dust! They are selling it for $7.00. I picked one up and really like how it aids in quick mag change. http://www.glockmeister.com/Glockmei...oductinfo/BCI/ glockmeisterbci2.jpg

That gap actually has a purpose. If you were taking your Glock through water (streams, rivers, oceans, etc.), it allows water to drain from the upper slide assembly and out of the pistol. It also allows debris a place to escape from the slide area as well. If you plan to keep your Glock on dry land or away from any serious water hazards then plug away!

That opening is also there to allow you to get a grasp on the back of the magazine to pull it out if it gets stuck. If you plan to keep it spotlessly clean and shoot only clean burning factory ammo in it, you might never need it

I have a plug very similar to that and really like how it guides the magazine in, I have no problems getting a good grip to strip a mag out during a doublefeed.

Butt-plugs... perfect.

I'm sure this has been said before, but I'll say it again here. The hole in the grip is almost certainly there to create uniform wall thickness for injection molding. The other "purposes" (drainage, debris escape, pulling out stuck mags, emergency round storage, etc.) are just icing on the cake.

But maybe that's just the engineer in me talking.

Some people somehow got the idea that it's an "exhaust" port. Or a channel to allow dirt and gunk to fall out of. I don't know where they got these deluded ideas.

Got one in OD... Anyone seen one in FDE?

Probably from some marketing guy who had to come up with a reason for it. Kinda sounds cool but not exactly true. So butt plug away...

I laughed at the idea of someone dragging their pistol through the river, ocean, or other body of water. Where do people get their tacticool operator dreams. I've been shooting a good while now and have never once had to do the drop and roll on some roaming oversized guinea pig that tried to attack me.

In the 20 years I've carried my Gen 2 Glock 23, the only thing that opening has collected is lint!

I haven't either, but after having seen some folks have their Glocks stop during IDPA and trying the extract their magazines by gripping the sides...I'm beginning to see why it might be usedful.

I've used a butt plug in my G19 and found the bevel doesn't help my magazine changes...but then I'm not indexing the magazine body on the rear of the magwell when shooting Glocks

But maybe that's just the engineer in me talking.

The question would then become, why did they mold in the half-moon shape on the rear wall of the magwell, if not to allow purchase by the thumb?

Well...

Once you get past the black-top, or climb off your 4-wheeler, things can get pretty "Natural"... quick.

Crossing creeks, swamps, and bayous, falling gettin' out of, or into a bateau (laugh, happens all the time on muddy banks) or stand, or just bein' caught out in an inch-a-minute downpour, will test gear pretty well. (There's a reason Ft. Polk is still around)

Now, I don't know about just why, exactly, Uncle Gaston designed his genius the way he did...

...but it seems to work just fine for me, as is, all the time... since 1993.

^^^ bought into the marketing excuses.

Correct. You'll find this in the other threads (see 2nd post) from Glock Armorers. If the back of the grip were solid plastic, it would not cool at a uniform rate with the rest of the frame and this would apparently cause issues. It would also weigh more. This is dead space on the gun and it's hollow because the frame is injection molded. It isn't plugged or capped because the cap serves no purpose and costs a couple cents.

The question would then become, why did they mold in the half-moon shape on the rear wall of the magwell, if not to allow purchase by the thumb?

It's a half moon shape because the inside of the magazine channel is square, because the magazine is square, and the back of the grip is rounded, because it fits your hand better. If your hand were square, the hole would be square instead of half moon. There is no purpose or utility for the shape of the hole -- it's simply empty space and its size and shape is a result of the desired width/length of the grip. If the gun were made for people with teeny tiny hands, they would have simply removed that entire area altogether and the back of the grip would be the outside of the same piece of plastic that the magazine touches on the inside. They space it off to fill your palm, and it's hollow because hollow is lighter and allows for even wall thicknesses, which is better for injection molding.



I think the consensus has always been -- plug or don't plug. Doesn't matter. Mostly aesthetic. BTW if I had a Glock I'm not sure I would actually think of doing it, but I do think it looks cleaner plugged.
