Mag Extension for Glock 43

I carry the Glock 43 quite frequently and I was looking for the right extension that allows me to carry a few extra rounds, but also feel comfortable in my hands. These were fairly easy to install using hte video from this page. Newer factory magazines may give you a bit of a hard time, but with a little extra force you are able to remove the bottom plate. I would recommend these to anyone who has hands bigger than what the 43 is made for and to carry a few extra rounds.

I've recently purchased the Glock 43 and I've come to the Glock Store to modify my weapon. One of the modifications is the +2 extension for several magazines. It's a very well made part and once you get it all together, you can feel the quality. It was a little tricky getting the spring insert to seat; however once that was done all you have to do is tighten the screw on the back. Only issue, the new magazine will not seat into your weapon if you've also installed the Grip Frame Insert. I'll take this new +2 extension over the frame insert, but this could be solved by a shorter screw.

I bought two of the 2rd extensions and love them. Highly suggest this product.

Using mine with SS80/G43 that has a grip plug insert so at first the black 6-32 screw was hitting plug and no-go. The screw was only seating half way and stopping hard. So, I ordered a 6-32 bottom plug tap and used a pin-vice to hold it to allow tapping set screw hole 3/4 of the way. Be sure to use tap lube or micro dot of gun butter when tapping. Once tapped, the set screw fully seated and with a drop of 222 Loctite and leaving about 2 turns exposed to hold the mag from sliding off, there was sufficient clearance to seat the mag in mag well and lock in. An easy fix and hope GS can tap these deeper during the manufacture process.

Use this on a G43. Got the extra strength spring, too. A trick to get on, but when done it's there to stay. It adds weight. The mag with all 8 feels about as heavy as the rest of the gun. For me that's a good thing. The extra weight in the hand, plus a new tungsten guide rod changes everything about the accuracy of this awesome pistol. I use this setup for plinking at 25 feet. If I carry, I put in the factory Glock extended mag to shed bulk. I am so glad to have the right to shoot guns in America.

Picked one of these up (the +1) and got the silver version but after looking at it wanted black so I got some flat black spray paint and painted it - it looks great now. Relatively easy installation and gives more room on the grip which is huge for the G 43.
