I carry a Glock 26 daily, in about the position you describe. I have been happy with my Galco Ultimate Second Amendment. Their website is not clear if this exact holster is available for a revolver, but it might be worth a look. I haven't had my glock shift or do anything else strange. I wear a light shirt un-tucked, over blue jeans, and the pistol hides very nicely.
