There is one other reason to have a snub: convenience of carry. Even if you are in a rural area its convenient to have your handgun in your pocket instead of in a holster. You might stop at a gas station and want to go into the store but then you have to remove your holster first.

If you get injured and need to signal a buddy to come help, you can fire your gun off to alert him to come help you. Handy to finish off a deer or boar as well. I always have a .357 and/or a .22 in my jeans pocket when I'm afield.
