Plastic putty/filler/cement

[Bushrod]

I'm not a modeler(not enough patience), but I think that you would be the guys to ask. My Sig 226 has plastic grips. For a double stack pistol the grips are ivery comfortable, so I'd like to keep them. There is only one problem-there is a bit of "flex" along the rear seam where the heel of my hand fits. Is there some material that I could reinforce the inner surface with-without melting/dissolving the plastic? It would have to be strong enough to take the shock of recoil while being immune to oils.

I haven't touched a gun since Her Majesty no longer required me to do so some seventeen years ago and my knowledge of such things is limited, but it will have to be something itself flexible if you are not to store up more problems for later on. The materials natural tendancy to flex will remain whatever you do. I would suggest fixing a plastic brace to the inside surface with an epoxy rather than cyano. You could try welding plastic to plastic with a low heat soldering iron but you would most likely end up ruining the thing.

Have you thought about removing the grips, filling them (or running a bead along the edges) with "Goop" (vinyl-type sealant) and reattaching the grips? Goop dries pretty solid/dense, but remains flexible, so it would more than handle recoil. Since the grips are plastic, I think, if you weren't satisified, the Goop could be pulled off fairly easily (and I'm sure it would not stick permanently to oiled metal), so even trying it wouldn't permanently mess up your piece.

I think what you want is RTV availible at most auto suppy stores. It is strong but flexible.
