Are you in business making holsters, or is this just a hobby?
I know for a fact KT has provided dummy guns to some holster manufactures that post here. In fact, the first photos we saw here of the SG P3AT were holster makers dummy guns.
Perhaps you spoke with the wrong person.
There is another company that makes cast aluminum? holster molding guns.
But danged if I can remember the name of them right now.
