If you do choose either the Blackhawk or the Super Blackhawk (the .44 mag version of the BH), you might want to look at used revolvers. The BH and the SBH are so rugged that it would be hard to damage one unless it was used often as a hammer for large nails.

The SBH is fairly easily found on the used market. The BH can be found but it does not seem as common as the SBH.

If you choose the .357 BH you can use .38 Special ammo for light loads, and the SBH can fire .44 Special ammo. .38 Special ammo is usually easy to find at a good price.
