But I also carry a second handgun, typically a light snub revolver, in a concealed location.
this is exactly what i do as well.
i came to that conclusion because in the event of injury, the other person--if having to walk out alone--is also armed.
an additional incentive for me was the idea of being in a remote wilderness location--and having the primary rig experience some type of damage or failure, etc., which might potentially render it inoperable--a second rig, such as a small, powerful snub, can carry the day...
