This holster was designed last year after I had several customers with Glock model 23s wanting a holster just a little smaller than the large auto. It is very similar to the MGP1, Large Auto with Mag Pouch, with the exception that it is an inch shorter in overall length and the mag pouch is ½” shorter. It has a 1” heavy nylon webbing thumb strap and high quality side release buckle to secure the gun into the body of the holster. Many full size semi-autos will also fit into the holster with adequate coverage of the end of the barrel. This holster is quickly becoming one of our best sellers.
