Thanks for the advice guys, y'all are awesome.
As far as the closed muzzle, I'm thinking that would be a customer option (open or closed muzzle), with disadvantage made known beforehand. I do like the looks though, and it would be ok with proper maintenance.
Good point about the belt slot being way out there, my thinking with that was the farther apart the belt attachment points, the more stability you'd have. Maybe not though.
Big O, that upward stitch at the front sight is actually my F-up, I meant to make it straight all the way down. In reality, I molded a front sight channel inside the holster, so no snags to worry about.
Thanks again you guys, I will proceed with new knowledge.
