I'm making a shoulder holster (my first), and would appreciate some strap advice from you talented people. I'm planning on making them out of 4/5 oz 1" strips of back leather. Of course I'll want them to be adjustable so i'm planning on incorporating double loop sliders for this, however I'm not sure which ones I should get. I'm afraid that I will get my strap all put together only to find out that there's not enough friction in the slider to hold the adjustment. I've seen some that have a center bar that slides which would seem to sinch tighter on the strap, but I do like the styling on some of the other fixed center sliders; anyone have any ideas, and links to where I can purchase the hardware?? I have not officially started my company yet so I have no tax ID to work with wholsale-only distributors like Ohio Travel Bag so i'm out of luck there for the moment. Also since i'm kind of strap stupid, anyone have any instruction or links to good articles on the purpose and proper use of hardware (certain buckel styles, sliders, dee rings, etc...) ? Thank you much.
