FYI, I recently ran into something called the Quick Draw Gun Magnet sold by Arizona Armor. It's a powerful plastic coated magnet with a grommeted base that can be fastened either by screw or nail or with velcro to attach a firearm just about anywhere it will fit. I've got one in the side pocket...
I think it would be helpful for those browsing for a holster to be able to see from the item title whether a holster is LH or RH or ambi right off the bat rather than having to click on the thread only to find out it's "wronghanded" or having to PM the owner of the item to find out.
