sp101 - strongest 5 shot snubby: a bit big IMO
security/service/speed-six - six-shot, k-frame size, stronger but compact enough to CCW
gp100 - six-shot, l-frame/python size, duty gun for steady diet of magnum loads (qualification/practice/carry); too big for me to CCW other than in shoulder holster
redhawk - six-shot maximum loads for anything the .357 will take
i think the security-six might be the perfect duty gun, i prefer the python, but i'm strange...
