Looking to purchase a (probably Kramer) OWB holster for a 4" S&W 64 (DAO). I have plenty of experience with different holster designs for autos, but I've never had a serious holster for a revolver. Most likely use is range use, but I would want it to be reasonably concealable under a fleece vest/hoodie/flannel. Clearly, round guns are shaped and built differently than square guns, so I'm wondering if there are any obvious advantages to, say a vertical scabbard vs. a pancake style vs. tunnel and loop (Askins Avenger style)...? Cant vs. straight drop?
Thanks for any wisdom you can pass along!
