I bought this a little after a got my KWA M9, seening as I needed a way to carry around my secondary. The first thing I want to point out is the construction: It's made of very tough fabric that is solid and doesn't scratch your pistol or anything goofy. It seems like it was made for my M9 seeing how I tried it with my WE 1911 and it jostled around a lot when I tried walking around my house with it. Mine came with a snap button and a velcro that holds the gun in the holster but I just flip the velcro over on the side and use the button because it's two different hand motions to remove both the button and the velcro. It's super easy to adjust eventhough I needed to adjust it 3-4 times before I got it just right for my leg. I really like the QD feature for the straps so I can still have the clip on my belt without having to undo my belt to put it on and off when I'm in the waiting room. I haven't tried yet but I think it will fit on a MOLLE vests, but I'm not entirely sure.
Overall if you're looking for a cheap, robust leg drop holster for a larger pistol, this product can't be beat.
