Safriland 577 gls holster works for styer m9a1 - Safariland 577 Pro-fit Holster

This holster definitely works with the styer m9a1. I ordered the 577 gls and yet the order said 576 once I submitted it but the 577 is what cane. I had to turn the adjustment screw with the tool it comes with like 3 times to tighten it and the m9a1 popped right in and wouldn't come out without pressing the button on the holster. I also had a level 2 light ready duty holster to fit my glock inforce alpc(that holster is made from ktmech) so I could also have a gls option for when the light is attached. Both can use the gls clip. Its great to see there are several options for a styer m9a1. You just might have to have something made like i did from ktmech if you want more security than a level 1 holster.
