This BE-X dropleg holster from Begadi is available for those who prefer the left side... "Tactical dropleg holster for medium sized pistols (Glock, P99, USP, Beretta and so on - NOT for Desert Eagle). Made from durable nylon. Through the suspension by two tiltable straps we achieved a better stabilization of the platform. Together with the stabilizing loops on the back of the holster these straps ensure that the holster fits more firmly and more stably during movement, Thus there is far less centrifugal force  transfered to the users leg, lowering the fatiguing effect of most holsters.

The straps can be attached to normal belts and into MOLLE systems both alike. The pistol is firmly secured in the holster by two systems. Directly over the weapon an adjustable strap secures the weapon with a pushbutton-release. Over it reaches, as 2nd cover, a latch, which is easy to open and close with one hand due ist quick-locking mechanism. This cover latch is removable, if preference of fast access is given more priority than security/cover. All belts and straps have velcro attached to secure them, so that no distracting straps need to be duct-taped away. The Holster has also a magazine pouch, which takes up two-rowed magazines."
