So, today I was talking about making holsters out of different plastics with my dad tonight, and he thought that there would be a cheaper way to do a holster other than Kydex. He said that spray foam, similar to Great Stuff, could be injected into a mold, to create a holster. Now, I feel that Great Stuff would be too fragile, and soft, but what about something that hardened a bit more, and held a shape better? Could something like that work. Link to great stuff, I know sometimes Home Depot mobile can be a bit weird: http://m.homedepot.com/p/GREAT-STUFF-16-oz-Gaps-and-Cracks-Insulating-Foam-Sealant/100003351/ And for those that don't understand how the molding would be done, I would have a box, with the gun suspended inside, and then the substance would be poured or injected in.
