Well, If you're going 5 oz heavier to the SP101, why not add another five and get into a medium frame revolver like a M10 or M19?
Jeez, for only five more than that how about a M686?
Or, for a few more, an N frame?
Or wait, how about a Super Redhawk?
Geo, consider that maybe the J-frame is all some can carry in certain situations.
Maybe they're already stepping up from a .22, .25, or .32?
A difference of a few ounces, or a half inch or so, can affect concealability/totability.
Obviously you like the SP101, I do too, but don't knock those of us that chose to carry a J-frame snub.
