Pull the dot snaps.
Pull the Dot 4 Pc Snap Set - Springfield Leather Co. Inc.
And I also recommend Springfield Leather far and above Tandy. Great company to do business with. There are youtube vids about attaching and using the pull the dot snaps. They are certainly more expensive, but they work. I tried using Line 24's on my IWB tuckable loops I'm working on. Complete failure. Went with PTD's and they work like a charm. Now if I can get the magnets figured out, hehe.
