A couple months ago I picked up a “Grip Force Adapter” for my Glock 19 to hopefully rid myself of the slide bite issues I’ve been having with the pistol. For about $20 at my local gun shop, I grabbed a package that contained a smooth adapter, and a ribbed adapter.
The Grip Force Adapters mount to the backstrap of the pistol using an elongated pin that goes through the trigger housing, and extends into the adapter.
The adapters work as advertised, and both styles keep me from getting slide bite. I also really liked the aggressive texture that is on the backstrap of the adapters which helps me to get a nice secure grip on the pistol.
The downside of the Grip Force Adapter, when mounted on my Gen 3 Glock 19, is that it makes the grip of the pistol huge when mounted. I have pretty big hands (every pair of gloves I own is size XL), and with the GFA mounted on the pistol I have to shift the pistol pretty far in my hand to reach the magazine release. The added girth also shifts where my finger lands on the trigger, which immediately caused me to drift my shots to the left. I could train through this, but I’m not sure it’s worth it.
At the end of the day, the Grip Force Adapter is a fine product, but it just doesn’t work for me. I’ve been slowly switching over to the S&W M&P line of pistols because of the slide bite I get from my Glocks as my grip migrates higher and higher, and I was hoping the Grip Force Adapter would remedy this. It did remedy the slide bite, but caused other issues…
For under $20 I think the Grip Force Adapter is worth a try, but if you don’t have really big hands it may not be for you. It’s well executed, and works as advertised, but it just doesn’t work for me. I do suspect that the GFA would work better on a Gen4 pistol which has a smaller grip, and a bigger magazine release. If I get the chance to try it on one, I’ll report back.
