This page is intended to document the best practices that I have found for modifying the grips on Glock handguns.  It is NOT an encouragement for you to modify your handgun.  If you do so, you assume full responsibility for that action, and you will void your warranty.  This page is provided for information purposes only.

WHY?

Well, I've gone this far, may as well go for broke, eh?

The gun on the left is an Airsoft gun that I used to experiment.  I lightly sanded the grip, then applied Aqua Mend.  I used a half of a half of a stick.  I rolled it into a cylinder, applied it to the grip, gripped the gun and squeezed for all I was worth.  This did NOT work.  It felt great while I was applying it, but once it hardened, it was evident to me that the 'mass' of the palm swell was too far forward.  It was hitting me in the joints of my fingers instead of the center of the palm.  It was, however, encouraging enough to try on the real gun - the one on the left.  I started the same way, but paid attention to make sure that the 'mass' of the swell had a bias to the rear.  This worked, but it was WAY too large.  I tried to shape it, but in the end, I ground it off and started over.  That one didn't work either, so I ground that off and then came up with the best practice.

You can see the bias on the real gun (left) to the rear.  This seats the swell well into my palm.  The way I accomplished this was to use half-of-a-half stick of AquaMend, roll it into a cylender, and then put it in my HAND, not on the gun, where I wanted it to be.  THEN I gripped the gun and squeezed with one hand only.  Squeezing with two hands caused the hand to collapse and push the swell forward - which ruins it.  I then shaped it with my fingers and kept feeling it until it was good, and then I let it dry.  After that, I shaped it by feeling it and taking off the high spots.  I kept taking off the high spots until it was perfect.  Then I applied the bed liner.  Ugly to look at, delightful to hold.  The grip is AMAZING to shoot with.  I put 300 rounds through it in quick order and my hand was not tired.

Airsoft on the right. 

Airsoft on the right - too far forward. 

Airsoft on the left.  Real gun on the right.  Very ugly, but shoots like a dream - which is the whole point.  If I wanted a gun to look at, I wouldn't have bought a Glock.

This is the left gun.  I wanted the left gun to be bi-lateral.  This idea came to me in a dream many years ago.  I actually have a set of hammers with this bump, and I used to have a set of swords made with a similar idea.  The bump is half-of-a-half-of-a-half of a stick of AquaMend - so 1/8th of a stick.

OK.  The story on this is that it's REALLY good, but it's wrong.  The bumps are too low.  I *very specifically* figured out where they should go.  The highest point of the bump should be in line with the top finger groove 'bump', so my palm swell bumps are 1/2 inch low.  The Universe was obviously trying to teach me something, and experimenting with it I find that it's really good, but I still want them to be 1/2 inch higher.  The are just the right size, IMO, and I REALLY like this.  I put 100 rounds through it, and it feels OK even though they're a little low.  They certainly look better than the fully molded grip.  I need to grind them off and begin again. 

I am not sure which I like better.  Each has a benefit and a drawback.  The fully molded grip is a little better to shoot, but it's not easy to use in the other hand.  The second experiment is the same in either hand, and it works well with a two handed grip as well.
