I happened to call him yesterday in the early evening out of the blue to discuss an idea or two I had regarding the metal spring clip and fitting the holster to both leather and nylon gun belts. Naturally, Tom not only had given those subjects thought already...but had already been tinkering with solutions, both elegant and those of a more Rube Goldberg nature.
Add to that that Tom always makes your phone call seem welcome and is generous with his time and it's an overall experience that's hard to beat.
I picture him as a mad scientist in his kydex holster lab always just a few little touches away from the next cool thing.
