Anyway, thanks for the feedback. Seems like a pretty big opening in the market. I'm surprised that with the relatively low cost of aluminum manufacturing, plus all the cool finishes and hydrographic designs people are doing these days that someone hasn't introduced a competitive product.
Heck, I think all of us revolver enthusiasts would even buy a plastic version if the price was right (under $10) and we could tack it on to a Midway or CTD order.
Are there other options? A quick Google search brings up BK Grips, which appear to not like chemicals.
I have an old plastic Pachmayr grip adapter, which is what I'm currently running, but I've heard the plastic can get brittle over time.
I bet I could get Shapeways to 3D print a set in steel for less than $100.
