I have a hodge podge of different holsters. I have an old and cheap Uncle Mike's shoulder holster that fits the biggest of my revolvers with an optic. I recently got a holster from Wild Guns Leather Company -- an original Dirty Harry shoulder rig that's really comfortable. I have Galco belt holster, and one of my favorites is a custom shoulder rig that was made for a friend of mine by a saddlery shop.
