The material is more like the polymer that is used in modern handguns. I'm no chemist, but after using the BK grip, I favor them.
For the chemists out there, the specification given for the 2-part urethane I use for these adapters is a Durometer (hardness) of 72 on the D scale, and a tensile strength of 3,200 psi. I'm NOT a chemist, but I've seen 72D described as "bowling ball hard".

Once cured these things are truly hard - if I wait more than about 20 minutes after they come out of the mold to try to carve off the sprue and parting line flash, they're almost too hard to cut with a knife, and I switch to a spiral mill in a Foredom tool to grind away what needs to go.
