I've got a Simply Rugged for my Glock 40 MOS I really like.
I didn't care for the greenish finish of the Cape Buffalo leather they offered as an upgrade so they stained it a very nice burgundy Ox Blood I see they are also now carrying for the cape buffalo leather, or the traditional greenish color: your choice.
I used the Cuda style holster and once you get all the strapping for the chest carry, you can just get a different holster to change out it as needed. The Cuda is for autos. For a revolver you'd need to go with the sourdough pancake holster.
