My Review of the Fab Defense FGG-S-K

'Model Confusion'

Before anything else, let me just warn everyone that I find the details for the FGG-S-K to be highly confusing. I bought the grip from the Zahal.org website, and there the model description is the "FGG-S-K", but the actual product in picture is actually the "FGG-K" (click on the link below to access the page):

"FGG-K" I presume means "Folding Grip Glock - KPOS" because it is used mainly with the KPOS Carbine Conversion Kits that Fab Defense also sells. The difference between the "FGG-S-K" and the "FGG-K" is that the former has a protrusion that allows it to index to the lower side of the frame and the front of the trigger guard. The "FGG-K" lacks this feature, and looks "cleaner" in appearance.

I also have a hard time finding any official and direct reference to the "FGG-S-K", even from the Fab Defense website, or its sister companies (CAA Tactical and Mako Group). So right now, I don't even know exactly what "FGG-S-K" stands for. I like products from Fab Defense, I have used a lot of it on my Glock, and they have all been quite satisfactory. So it sorts of mystifies me as to why they end up with a mess like this. 

 
'Comparison with FGG-S'
When I bought the Universal Scope Mount, I decided to also upgrade the vertical fore grip I am using with my Glock to the FGG-S-K. I first came across a variant of the FGG-S-K, the FGG-K on the Generation 1 KPOS that I used a couple of months ago, and I liked it better than the FGG-S (Folding Grip Glock - Small) I was using for a number of reasons.

First is that it is more of a regular shape than the FGG-S. The FGG-S has a highly irregular shape, lots of curves in the shape of the grip. I think it is supposed to make the FGG-S more ergonomic, but sort of accomplished the opposite as you end up with some gaps on your grip that tends to rob the grip of control. 

Another reason is that the FGG-S-K has more surface area than the FGG-S, and that additional surface area combined with the more regular shape allows you to have a more comfortable feel and more control of the grip. Overall the FGG-S-K also looks just much better aesthetically than the FGG-S. 

It's hard to know for sure due to the lack of detailed information on the history of these vertical fore grips, but I suspect that the FGG-S is an older model or design, while the FGG-K and FGG-S-K are the newer models or design.

'Other Features'
Just like the FGG-S, the FGG-S-K can be folded and unfolded by releasing the lock at the side of the grip. There a little bit of play or wobble when the grip is extended, but not too much that you would notice it during firing sessions. The lock is also quite durable, and solid, the slight play has remained the same despite numerous firing sessions with it.

The FGG-S-K does have one thing that the FGG-S does not have, and that is the ability to extend its length thru a retractable portion of the grip. Extension is simple, just pull the retractable part out. It has ratcheted stops that allow you to incrementally increase the grip length by a couple of millimeters at a time.

Retraction is simple, just push the two buttons on both sides of the grip at the same time. It is spring-loaded, so it will retract on its own. The fact that you need to push two buttons at the same time also ensures that the grip will not easily or accidentally retract when you don't want it to.

'Trigger Safety Feature'
Another feature on the FGG-S-K not found in the FGG-S is that it can be used as an additional safety feature for your Glock. When folded, it covers the entire trigger guard so you will not be able to fire the gun. 

This has both positive and negative features. Positive in that there will be no way the gun will fire if the FGG-S-K is folded, but also negative as you will need to unfold the grip in order to have access to the trigger. You can get that folded grip out of the way using only one hand by flicking it downwards with your index finger. It won't unfold all the way down, but you will have access to the trigger. In order to unfold it fully, you will need to use your other hand to do so.

'Parting Shot'
Except for the fact that the FGG-S is smaller and more compact, and allows you to fire the gun even if it is in the folded position, the FGG-S-K is superior is all of the other aspects such as looks and functionality when extended. I am not sure due to its hazy history, but I think the FGG-S-K is the "newer" model compared to the FGG-S, and I would guess it is the "improved" version in most aspects. Between the two models, of course I will choose the FGG-S-K at this point, and plan to hold on to it and keep it with my Glock for some time. Below are some pictures of the FGG-S-K as attached on my Glock 22.
