Nice job and a very good idea. After a few recent posts showing very nice adaptable chest rigs for cross draw holsters, I have been kicking around this very thought. Al my hip holsters have a 15 degree forward cant. This should adapt nicely for that. Thanks for the idea!
I have 2 now. A siphon and a gravity fed. Both inexpensive, and both doing alright. I use a moisture trap and always spray before I get to the project. I'm new to this but really like the shading I get.
I use one of those. The first one broke the frame where it meets the handle. The second one (replaced with no issues) has held up much better. Your's does look uneven. I'd try for a replacement. I put mine on the buffing wheel from time to time.
