I'm trying to decide upon a revolver to be used for handgun hunting black bear. So far, I've come up with a caliber of .44 Magnum and a disired barrel length of 6." As for sights, I'm thinking a white outline rear, and orange front. Optics? Maybe a red dot, but I would at least value the ease of install. Being that I'm in Mass., the widest selection of revolvers I have to choose from are available from Ruger, and S&W. The choice between SA or DA I'm not certain of. I like the SA Rugers, but a DA seems to make more sense in this situation (pursuit of deadly game). I've carried a 50 oz. handgun, and it wasn't too bothersome, so weight isn't much of a concern. My hike ins will be in the neighborhood of 5 miles. Any suggestions or observations to offer?
