Glock Frame Modifications Gone Wrong - Update!

Hi All, I am looking for some advice.

I really like the look of Glock Gen 4 frames with the finger groves removed and with the grip surfaces stippled and polished. I am usually pretty good with my hands, and I have had a fair bit of experience working with wood, sanding, polishing etc. so I thought that I should be able to preform these modifications myself. I did some research and found examples of all the modifications I was hoping to preform which included milling out material from around the magazine release, making in easier to get the button fully depressed. Unfortunately, I failed to realize that while performing this modification on a Gen 3 frame will produce great results, this same modification on the Gen 4 will seriously impede the function of the magazine release by allowing play into the button itself. The button now hooks around the frame, and drags/clicks every time you use it.

I was pretty disappointed when I realized my mistake, and decided to buy another frame to ensure that I have a fully functioning pistol. This being said, I would like to repair the frame I have ruined.

I have tried bonding epoxy, and a uv light activated polymer to the frame in order to replace some of the material that I have removed but these compounds do not form a strong enough bond with the Glock frame.

Do any of you have experience bonding material to a Glock frame? How did you do it?

Eeek ... well, there are aftermarket and extended mag releases that 'may' help, as I've had some that were a stiffer fit than factory. My guess is you'll need to have a look around, and possibly contour the mag release (button) itself. Lots of gap there :(
 
I've had mixed success with JB weld. You could build the area up to where it was and then file/sand it to shape. Try some in the inside of the bottom of the grip to see how it bonds. That hole in the back / bottom of the grip if Glock still has it.

Clean area with MEK or Acetone before trying to bond.

Why would you enlarge the actual opening of the mag release? Not like you have to stick your finger in there.

I didn't make the opening any larger than it was originally, just took some material off the top to slope towards the opening. The hole is the exact same size as it was originally.

Depending on your skill set, it might be easier to fabricate a new mag release. That's probably what I'd do, anyway.

I thought the same thing as you did and fabricated a new mag release. Unfortunately, the modifications to the mag release that would fix the problem will not allow a magazine to enter the frame. The repair needs to be done to the frame itself.

Thank you for the advice! I will try the JB Weld with the Acetone prep. I will let you know how it works out.
 
Hi All,

It has been awhile but I have successfully repaired my G17 frame using a small amount of JB-Weld.

I found some JB-Weld specifically designed to bond with plastics and built up the material around the magazine release. After I had the required material in place I was able to file the JB-Weld to the final dimensions. After I got it finished, I painted the JB-Weld with some black nail polish. This repair has completely restored the functionality of the G17 although cosmetically it is now slightly flawed.

Thanks again for the advice guys!
