Each webpage lists a left-handed holster, so no, I didn't mis-read your question. Typically, only one photo is listed for a product. Usually the photo shows only one firearm in a right-hand model, even though other firearms and left-handed models are also available.
For the Galco site, see the box entitled, "You must select an option if any".
For the Fobus site, see the model number "WA99LH".
