I picked up a GP100 7-Shot revolver with a 2.5 inch barrel. I have found numerous holsters online that claim to fit the GP100, but the listings do not specify if they fit the 6-shot model, the 7-shot model, or both models. Any recommendations from other owners would be greatly appreciated. I prefer leather, but cannot afford to be picky given the limited number of options. IWB or OWB is fine as long as the holster is comfortable and reasonably concealable.
