Installing a Pearce Grip Extension On A Glock 29 Magazine

The first thing I noticed with the Glock 29 with its stock 10 round magazine was that the grip was way too small for my hands. Granted I wear XL sized gloves and have big palms courtesy of my dad and grandpa but literally, my pinky finger had nothing to grab on to and I really didn’t want to control a 10mm pistol running hot loads with just two fingers – excluding my trigger finger that is. I had a trick up my sleeve though – I knew I could get grip extensions that would make holding the pistol way more comfortable.

Yeah, sorry, I can’t stand this kind of grip.

The solution comes from Pearce – they make a really nice injection molded base plate replacement that gives us just enough of an extension to comfortably hold the pistol. Since Pearce released their’s some knock offs have come out that look identical but I stick with Pearce.

That little lip makes all the difference in the world.

How To Install Them

There’s two reasons for this post – first is to tell you that there is a grip extension for the 10 round magazines and the second is to give you a tip on installing them that will save you some real grief and this pertains to Glock mags in general.

On most magazines, you push the locking button down that holds the baseplate in position and while you are doing that, you then push the baseplate off while capturing the floor plate and spring so they don’t come flying out. Trust me, those suckers can come out like a rocket.

A Glock is close but not quite. Everything I said above is true but there is also a ridge case in the middle of the magazine’s rails that the base place slides on that makes it an absolute bear to do without a Glock magazine tool. Honestly, the first time I went to disassemble a Glock magazine I could not get it off and then started searching – people said to get the tool. I thought the tools were a scam because I never needed one before other than something to push a recessed dimple down or pry off a base plate with 30-50 years of junk on it. Well, with a Glock magazine, you really need the tool and everybody and there brother makes them or imports cheap knock offs that work as well.

Here’s what you need- A G29 otherwise I don’t know why you are reading this :-), however many Pearce grip extensions and 10 round Glock magazines you need and you can see the magazine tool I use in the top left. Note, I can’t speak to whether these extensions will fit on any other brand magazine – all of my 10 round mags are Glock models.

When you look at the tool. it has a nose that pushes the dimple down on the floor plate while also allowing you to have enough leverage to then pry the base plate off thanks to the mechanical leverage it gives you.

I secure the magazine in a vise to hold it while I use the magazine tool to remove the base plate. By pushing down on the handle of the tool. you have enough leverage to remove the base plate. Go slow and capture the internals – notice how I am saying this over and over.

Again, be prepared to grab/capture the floor plate and spring assembly or they will rocket out. Yeah, I’m making light of this but a lot of people have suffered eye injuries from not being prepare and getting hit by the parts as they fly out.

The floor plate (the little grave stone looking plastic tab with the dimple on it resting on the wood vise jaw) that pushes the magazine spring down and also locks the floor plate in place is shaped to go in the magazine one way. You just need to make sure that little dimple is face up to lock the grip extension in place. If the grip extension doesn’t want to snap in place then you probably installed that floor plate upside down.
Reinstall the spring assembly and make sure the follower (the plastic thing that pushes the bullets up) is oriented properly. Note that the dimple is face up in the photo in order to lock the base plate in place. What I do is to hold the floor plate and spring with my thumb as I slide the base plate, or in this case the Pearce Grip Extension, on to the magazine tube. You will probably hear the dimple click ino the hole of the base plate or at least feel that the extension can’t move / that it is secure.
This is a good photo of the ridge, or tab, that is cast in the magazine’s body that really holds the base plate on and makes removal so hard.

This is the end result. Notice how my little finger can now firmly grip the pistol.

If you have big hands or just want to make the grip a tad taller for whatever reason, I absolutely recommend the Pearce Grip Extensions and have four of them on my OEM Glock 10 round magazines. I have shot a ton of hot Underwood and Buffalo Bore ammo and had no problem controlling the pistol. So far, they have held up just fine.


Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.
