Sound advice from Smokewagon! Does your 856 have a exposed hammer or a bobbed/concealed hammer? I carry a couple of 38 Special guns daily. Primary with a hammer is IWB at 4 o'clock in a Sticky Holster. BUG that has a flush concealed hammer, thus DAO; is in my pocket. YMMV, so experiment and you will soon find what works best for you.
What works for me is to carry mine in a kydex holster in my front right pocket. That may not be to your liking. There's a lot of ways to carry it. In the winter I'll have the 856 in my right front pocket and my 605 just riding in my offhand jacket pocket. Which is also something that may be to your liking. How do you normally carry, or do you normally carry?
I tend to prefer pocket carry in a holster for the 856 and speed strips. I wonder if pocket carrying an 85 is noticeably easier due to a smaller cylinder. I have also carried owb at 4 o’clock with an untucked shirt. For me I think the 856 might be uncomfortable for iwb.
