Everything is riveted. ( I call them rivets "gromets")
The Chicago screws attach the belt loops to the mag pouch.
This allows to change the size of the belt loops ie 1 3/4"-2" etc.
The magazine draw is smooth and effortless.
A full magazine inserted in pouch, "shaken upside down" magazine stays tight and seated.
Running full retard (although fun) is not going to be a realistic option. IMHO
Something to consider.......
ETA: Nice site you have here Thatguy, I see you have been busy.
