I called and asked what product these folks suggested making holster molds from and was told they suggested Vac Master 25. I have never worked with two part urethane before so....this was going to be a first! I had also never made a gun mold before so......it was really going to be a first! haha
Long story short, my molds held up and made some class act holster molds! Great product, wonderful results.
