Revolvers are very reliable, but they aren't foolproof. I can short stroke the trigger on my S&W 642 and advance the cylinder without firing a shot.
I've been and NRA Certified Instructor for over 12 years, teach Ohio CCW classes, and have a lot of training certificates in a folder from various advanced shooting schools. My personal opinion is to only use rigid holsters that stay open when you draw the gun. You want to be able to reholster the gun with one hand. Holsters that require two hands to draw the gun like the urban carry are a severe liability.
If you are looking for deep concealment, several holster makers have products that are designed so that you can tuck your shirt in over your gun.
I just bought one of these, looking for a more comfortable way to carry.
