I do think that the 10MM is one of the best trail guns available.
The 10mm is a cartridge, not a trail gun. The cartridge might be in the running if the trail gun a revolver. There are relatively specific needs that a 10mm in a semi-auto answer, but the overall versatility of the revolver make it a better trail gun.
It's [the 10mm] superior to the venerable .357 Mag for bear defense.
They're probably a tie for mediocre for that purpose.
