4sevens Quark aa2 Turbo holster help.

Hi guys, love the forum. Been reading it off and on for the last year on light reviews. Recently I picked up my 2nd 4sevens light, the quark aa2 turbo for work. Its joining my preon 2 for edc. This light is going on my duty belt for work but the holster that came with it isn't all that great. The Velcro doesn't seem to fully engage when the light is in the holster. Been looking around and haven't found a holster that would work. Any suggestions for a holster for this light? Preferably one with a snap to close the flap. Even an open top holster would work as long as it was a tight fit. Thanks all.
