I am in the market for an inside the waist band leather holster for my Glock 21 Gen4. There are a bunch on the market, some cheap and some very costly, but I know that highest price is not always the best. I want a leather one, hopefully won't damage the finish on the gun. I came across the OD Green version and bought it. I wonder if the hard synthetic holsters would rub on the finish of the gun. Anyone have a favorite brand of holster that fits my needs?
