The simple answer is that a person should take as much firepower as they can reasonably handle and direct. Lets look a little closer and consider some things: each time a guide takes clients out they face a hypothetical situation: Will there be an encounter, what is the likely situation and how could it unfold?
Looking deeper, it has been expressed that the gun and load worked, this time. What about next time? The article states the guide is capable of using an .357 and .44 Mag-likely proficiently.
Since he is familiar and capable w/such loads, isn't that the practical choice when one considers potential outcomes.?
Since you use a 10mm, you have voted lesser faith in the 9mm's ability. Would you trust a guide w/your life and that of a loved one in a similar situation? Why tempt fate? The article doesn't state the size of the bear but doesn't give any indication it was a mature boar. Next time could be much different with a larger animal and the extra power from a larger load would pay dividends. Life is important enough for one to use that giving them the best advantage for survival.
