I have a new in wrapper Raven Concealment Systems Glock 20/21 dual magazine pouch with the MD cut in black. It has 1.5" belt loops and is a great magazine carrier. It is intended for right handed shooter to be carried on left side with rounds pointing forward. This is a great piece of kit, I just happen to have two of them.
Email me if you have questions or would like to see photos. I am asking $65 shipped.
