Suitable materials that can add on to polymer frame?

[Byron]

Obviously removing material from a polymer frame is quite easy, but are there materials suitable to add to the frame?

Are there epoxies that would adhere satisfactorily to Glock polymer? (I imagine solid adhesion might be difficult, but perhaps roughing up the polymer would help?)
Are there multiple options of varying permanence/strength? No realistic options? Somewhere in between?

I thought RAT Grip made a product for Glocks (I remember watching a YouTube video on installation), however on their website they only have products listed for rifles...

No experience with them however.

ETA: Found it, it's called the SPRR Grip Kit. Video

There is a product that Brownells sells that folks wills and and stipple when they booger with backstraps on Glocks.


What are you looking to do?

Arcaglass seems popular for Glock modifications, but I've never used it on a Glock - only to bed a rifle.

Short answer: experiment with adding material near the mag release.

Longer answer: I have a well-loved Glock that has been abused with a dremel, soldering iron, and other implements. I previously removed a lot of material surrounding the magazine release, which has generally been fine (i.e. there haven't been any complications as a result). I recently changed out the magazine release, however, and don't particularly like how it now interfaces with my previous modification. I want to add just a little bit of material back. Don't yet know how much material... but want to experiment.

Lots of plastic welding systems out there. Welding nylon is pretty easy.

The West Systems G Flex epoxy has worked for me on a couple of plastic repairs. Haven't tried it on a pistol.

Spackle your crack! Just kidding... I've had success with JB Weld on plastics, but it's not the easiest thing to work with.

Thanks, everyone, for the suggestions. Looks like I have some reading/comparing to do.

Plastic welding looks pretty awesome, but is well beyond my capabilities (referring to both tools and skills).

I used the Acraglass on the inside rear of my grip-chop to make sort of a magwell/funnel/butt-plug combo. It is much harder than the Glock polymer. I did a lot of heavy roughing of the inside of the frame to make it bond well. It hasn't moved or had any problems since then. It was fairly easy to work with, but filling a hole where it's supported on all sides is obviously much different than getting it to cling to a flat surface on the outside of the gun.
