I use this with my KWA KP 45 and it works fairly well. The construction is decent for a $20 product, and it holds my pistol firmly in place. The additional mag holder works well; however, getting a double stacked mag in is a bit of a tight fit. Over time the elastic will loosen, and putting a spare mag in becomes easier. As far as the color is concerned, it has a slightly lighter hue than the rest of my OD colored gear - not a big deal to me, but may be for some. This holster has plenty of options for sizing modifications, which is a nice perk. One thing to note though is the strap used to secure the pistol - it's somewhat difficult to reach down and unbuckle during a heated battle. What I've done to help make the drawing process faster is to really cinch down the strap. Doing so allows the buckle to "fly" open when depressed allowing me to more easily draw my pistol.
That said, I have one major gripe with this product - it slides around a considerable amount. If you do a lot of running, plan on this holster being all over the place on your leg. Even during games where I'm not doing any running (a slight jog), this holster will start swinging around. I'm an adult (5'10" 175 lbs), and this thing won't stay in place for me, so I can't imagine what would happen for younger players who haven't filled out yet. The padded leg strap has a tacky backing to it, but it doesn't seem to help (perhaps two sets of straps would be more efficient in helping the holster stay in place.
