All depends what you're using it for...

hunting - revolver. Especially if you plan on traveling to another state, many don't allow the use of a semi-auto

conceal - personal choice. I have a ruger sp101 in the smallest version but i choose to carry a ruger lc9 far more often due to the reasons mentioned above. If I am out for a walk in black bear country, the sp101 comes along.

Nice to have more than one tool for the job.
