I have looked around and even read Brownell's article on grip reduction and beavertail mods. I'm still not sure what's the best way to proceed! Brownell recommends using Acragel for the grip filler and for the base material for the beavertail. 1. Is there a better material to use other than Acragel? 2. I read that Robar inserts metal into their beavertails. Is this a needed addition? 3. I'm wanting to heat stipple the finished gun. I'm assuming that I will need to Duracoat the frame to cover the beavertail and frame reduction areas, or am I wrong? Any additional links to how it's done and recommendations, would be appreciated!
