Because "Red gun" has 3 letter words I could not successfully search this topic. Forgive me if it is a duplicate.
For you guys and gals that do a lot of different holsters, has anyone thought of using the red or blue training weapons sold through police equipment companies as molds for their holsters. The are exact replicas of the guns they are meant to represent, there are many models currently in production, and they cost between 40 and 60 bucks. For a guy or gal who is not doing full production work but has the occasion to make holsters for the same models of guns on a regular basis, I think it would work great. You can also get red or blue dummy magazines for making mag holsters/carriers/pouches and the like.
Just an idea I had. Probably not the first but I thought I would offer it up just in case.
