I like a 357 mag while i have a 41 mag i still carry a 357 far more.
i have three 357's while the s&w 19 in 2 1/2 bbl a great gun (cause i have one) i prefer the s&w 686 in a 4" bbl. it's a little heavier than a 66 but it's my preference.
now a ruger gp 100 is a fine piece of hand steel and i wouldnt hesitate to give some green backs for one. some around here may find that strange but heck i like to be strange.[]
