| I'd like to experiment with the grip angle. How would you add material on a temporary basis? It would only need to last long enough to get a feel for it, maybe a mags worth of shooting. What would be the best way to do it permanently if I like the modification? |

There is a modelling clay sold in arts stores. It would be durable enough to stand up to a magazine's firing after hand molding.
To harden it, it is put in an oven at ~200F to cure it. I have form fitted Smith 52 grips that have stood up for +1000 rounds. Looks like crap, but the clay is as strong as the walnut grips. |

The clay will need to wrap around the stock in order to get a mold lock for attachment. Check the cure temperature first, you may not want to subject your Glock to temps over about 180F long enough to cure the clay. There's no way I would subject the frame to 275F.
Accraglas is Brownell's trademark for their epoxy bedding materials. Terrible choice for this task unless it's loaded up with a filler to make it sufficiently thick so the epoxy doesn't run. I've used baking soda, Cab-O-Sil, milled glass, sawdust, and micro balloons. Micro balloons are the only filler here that is easy to sand, although sawdust isn't bad if the content is high. Mix the filler in to make the paste as thick as peanut butter. If you want to get scientific, make the ratio of resin to filler about 35% resin. You can get a Corvette kit from Walmart or just a can of polyester resin and catalyst for this project. You're on your own for finding a filler, although I can tell you where to find micro balloons. * Baking temperature is 230°F for the new Fimo, and 265°F for an old version of this brand; * 215°F to 270°F for Cernit, * 275°F for Premo, Sculpey, Pardo, and old Kato, * 285°F for Bake & Blend, * 300°F for new Kato. Bake for 30 minutes per 1/4 inch thickness. This stuff is a bad idea for a plastic pistol. |

Use tape to modify the shape. Stick on strips where you want to build up, then add a wrap or two to hold the whole thing together. Unwrap to modify until you find a shape you like.
Or, you could buy an 1911 or HiPower manufactured with a proper grip angle out of the box.
