Glock 23 Machine Pistol Configuration Part Three

'Fab Defense FGG-S'
I chose the Fab Defense FGG-S Tactical Folding Grip over other picatinny foregrips out there, mainly because it definitely was made for the Glock in mind, as it does not only attach to the rails, but also on the lower part of the frame, and the front of the trigger guard. This provides more area to distribute the force applied of the foregrip. This minimizes the flexing of the frame when using the foregrip.

It even has a hook-like protrusion at the upper front of the grip that protects your finger from the muzzle blast. Another item I bought online, which arrived about a week later. The only problem with the grip, is that there is a bit of a gap between the FGG-S and the front area of the trigger guard. This gap allows the frame to flex a bit too much, increasing the gap between the slide and the frame, which I was afraid was going to cause malfunctions.

I decided to put some material to fill that gap between the FGG-S and the frame/trigger guard by using 3M double sided tape (used only one side, kept the backing of the other side intact). I used three layers of the 3M tape to effectively fill that gap, and they seem to work very well in minimizing the the flexing of the frame when force is applied to the FGG-S.



One thing to remember when attaching this grip, is to ensure that you don't overtighten the screw, as Glock says that tightening the screws too much of any attachment on the Picatinny rail will cause the gun to malfunction. There really is no need to tighten too much the screws for this grip, the screw is caught between teeths that keep it from moving back and forth anyway. So just use enough force to lock the screw lightly in place.


I found it hard to insert the screw straight on when the grip was attached to the frame, I just simply screwed it in slowly until it reached the other side.

The FGG-S wobbles a bit on its hinge, and is also a bit awkward to hold due to its hollow back. The gap between the grip and the trigger guard is also quite narrow, so I had to shift my thumb a bit to enable it to fit there. Nevertheless, despite these issues, the grip still provides a better area to put your non-shooting hand on the gun. It helps steady the Glock, and also helps in controlling the recoil and muzzle climb. Aesthetically, it looks fantastic, enhancing that "Machine Pistol" look of my Glock 23.

'Burris Fast Fire II on the Glock'
After a couple of weeks of waiting, my Burris Fast Fire II Mount for Glock finally arrived. It was easy to find stores selling them online, but the biggest problem was finding such a store that would ship such a part to the Philippines. I finally found one after a long, long search.

The hardest part in the process of installing the mount, was removing the factory, plastic Rear Sight out of the Glock's slide. I tried to tap it out using the Glock Disassembly Tool as I couldn't find a good plastic or wooden punch. The sides were deformed by the punch, so now it looks ugly. I think I am going to buy a punch made for removing/installing these sights next time, to keep me from damaging the sights.

The Glock factory Rear Sight actually has two parts: The plastic sight, and a metal retainer. The plastic sight will actually fell out first, and then I had to punch out the metal retainer. Once that is done, installation of the Glock Mount proved to be so damn easy. First, just wipe off any oil and dirt from the rear sight channel. Then insert the Dovetail Block that comes along with the Glock Mounting Kit. The Block fits loosely inside the channel, so no need to force fit anything in.

Then put the Mounting Plate on top of the slide, and align its screw holes with the screw holes on the Dovetail Block now inside the Rear Sight Channel. Then join both parts by using the supplied screws. The Mounting Plate not only grips the top of the slide, but also the radiused sides of the slide, forming a very secure grip of the slide. This also means the Plate automatically centers itself along the slide. After that, just screw the Burris Fast Fire II in, and you are ready to go.

I wanted to put the FF2 on my Glock after I noticed that I was shooting tight groups with it on my KPOS. The FF2 also raises the sightline by about an inch compared to the factory sights, allowing me to comfortably put my cheek on the GLR440's cheekpiece and still see the red dot clearly. The change in sightline to stock dimensions also enables me to sit the rear of the stock better on my shoulder, allowing for more control during recoil.

I actually had a Burris Fast Fire II Picatinny Protector, but it didn't looked "right" when I mounted it on Glock, it made the FF2 too bulky, too high. It disrupted the clean lines of the gun, so I got rid of it.
