Bizarre...

[Wanderling]

So, I installed a Grip Force Adapter on my G17 (the plastic beavertail).

It was a b#tch to install, it just wouldn't snap on the opposite end of the pin, I had to push it with a screwdriver.

I noticed that my accuracy went down. I wrote if off to switching to the TulAmmo from Federal.

Today, I went to the range and the gun was shooting to the left. There was also some wind but I figured it wouldn't affect the accuracy that much at 10 yards. I decided to take the GFA off, and I could swear my accuracy improved. (Accidentally, the wind also calmed down somewhat).

So, does it make any sense whatsoever ? I mean, as long as I aim properly, what I have attached to the handle shouldn't matter, should it ? Unless it somehow stresses / bends the frame & causing the slide to operate differently - but I just can't imagine it doing that. Glocks are not that flimsy.. or are they ?

I put GFA on because I tend to get bad case of slide bite. Drawing blood, actually . I grab the gun so that the web of my hand is right there on the curve, and the top of the knuckle on the back of my thumb tends to get in the way of the slide. Perhaps I just need to change the way I hold it...

The first thing I can think of is that by changing the grip you changed the reach to the trigger. Therefor changing where your trigger finger actually contacts the trigger.

Having too much or too little finger on the trigger can affect your straight back trigger squeeze, and cause you to pull your shots one way or the other. So you may have affected your accuracy inadvertently with a grip addition or change.

I'm not familiar with the mod you're talking about though , and I don't own any GLOCKS. So a picture would help. If it isn't a change in trigger reach, then I couldn't tell you.

Now that I googled it, I'd be willing to bet I'm right. You changed your trigger reach slightly, and screwed up your trigger control on accident.

It has almost nothing to do with the frame and slide.

What the GFA is doing is cause you to change the way you are pressing the trigger.

If the joint at the base knuckle of your thumb is interfering with the travel of the slide...getting hit...you aren't gripping properly and that would effect the placement of your finger on the trigger face

Thanks for help ! Will work on my grip.

Maybe your Glock is a vampire and needs your blood to be accurate. (what can I say, Halloween is coming)

May be it is... but shouldn't it pass some of it's super qualities to me with each slide bite ?

Now ya know it's just kool aid... Nothing special at all

So, I watched the video and the way I grip it is the same as the guy in the video - I just tend to forget to move my strong arm thumb far enough to clear the slide. By a small amount, but just enough to catch the very edge of the slide and get scratched.

This leaves me two choices:

1) spend time & ammo to adjust my grip to shooting without GFA

2) spend time & ammo to adjust my trigger technique to shooting with GFA

Since it seems the consensus is that GFA does not have any impact on the gun accuracy itself, I will try to do #2. I like the way the gun feels with GFA.

I appreciate everyone's help.

Well, I went to the indoor range yesterday with 3 boxes of ammo (2 of them the new aluminum cased ammo that Walmart started to carry). With GFA installed, and paying attention to where my trigger finger was on the trigger, I was able to hit the bullseye dead center at 25 ft within first 5 shots. Overall, I was shooting as well (or as poorly) as ever. So GFA stays on and goodbye to slide bite !

There you go man. Glad you're on the right track.
