with the huge amount of hand gun styles/makes you would have to accommodate is it safe to assume this is maybe a lash type system that is compatible with a particular holster maker?
ha, that was me...That didn't sound quite right so I went and pulled these from their statement on FB
"We can certainly do a 329pd and many other pistols as well as custom mold to any pistol that a customer sends us."
"Right now we have most Glocks, S&W M&P's, and some others available. We will not use blue training guns to mold from so we offer the option to send us your personal firearm and we can custom mold to it."
