Like BikerRN, I like one of the two to be a service-sized weapon, such as a 4" sixgun. But, in some clothing combos, two, or even three snubbies can be easily concealed where a 4" gun would be too much. FerFAL, your idea is quite valid, and many guys do just that. In my case, as my snubbies are Ruger SP101s with magnum ammo, it makes sense for my bigger weapons to also be .357. When not at work, therefore, the bigger weapon is usually one of my 4" sixguns. At work, my belt holster weapon is a double-stack-magazine autoloader by regulation. I could certainly carry my duty SIG P229 when off the clock, but I like the way a sixgun "rides" on my hip, and in the event of a rare long-range incident, I am more confident of accuracy with the big sixgun.
