I'm not a revolver fan. I think they are slow to reload, too expensive large and heavy for what they offer. The triggers are almost always too heavy for accurate shooting. The legacy of black powder cartridges means they cannot take easy advantage of low volume smokeless cases. Their reliance on rims or clips for extraction limits the few that are in modern calibers and the "More Power" crowd have demanded cartridges that have excessive recoil for defensive shooting.

There are a few advantages, in a limited context. Those powerful cartridges give the revolver relevance for protection against wildlife or use in hunting. The black powder cartridge length and operating method means they can be loaded with a variety of powders including black powder. Revolvers are almost always compatible with cast bullets, and lend themselves to saving cartridge cases. In short, a proper revolver is a reloader's gun and subsequently a good choice for people worried about a future without easy availability of ammunition.

And out in the real world, a revolver is probably good enough for home defense or personal protection. It can be easily employed at grappling ranges without jamming when fired in contact with the threat.

A good revolver should have a grip that you can wrap all your fingers around. If it has an external hammer it should be easy to cock, if it doesn't the trigger pull should be as light as possible.
