Exactly what I've been saying for years.
I almost never carry bear spray, unless I think I'm going to need it for a moose.
The trope of "I carry both, if the bear spray doesn't work, I can use the handgun" completely ignores the reality of how fast these incidents happen. There is seldom time for "less-lethal" experimentation in incidents where an attack is likely to be happening. If the handgun isn't needed, that's generally a nuisance bear and there's lots of things that are just as effective, or more so, than bear spray for those kinds of incidents, not to mention, plenty of time to decide how to deal with them if they occur.
If I recall correctly, the guide mentioned above, Mark Uptain, put his 10mm in his pack, or on his pack, and kept his bear spray on his person while cutting up an elk for his client. He only had time to use the bear spray, which didn't work. Had he kept the 10mm on his person and had the bear spray in the pack, he almost surely would have survived the incident.
