This is an IDPA compliant double mag pouch that fits most double stack 9mm and .40 SW magazines. By my experience, it fits G17, G22, and XD9 mags. The loop is a TekLok so it will fit any size belt. Asking price is $11 flat which includes shipping. This normally retails for $25+ I take cash, check, or money order (which you can buy at CVS pharmacy not just the post office). I don't take PayPal. PM me if interested.
