Preference - its up to the INDIVIDUAL
I own a few snubbies and they range from .22 RF to .38 SP,.357 Mag,.44 SP.
The one that gets carried THE most is not the one I like to carry,that would be the 360 as its super light and I can shoot 38 & .357's in it,BUT it has a hammer and that slows down my draw.
I have drawn it in live fire and snagged clothing with it,the pocket carry of the 442 is not as much fun due to extra weight [ 9 oz. v/s 14 oz. ].
But the hammerless 442 is MY prefered carry,due to its lack of a hammer.
yes I can do the 'thumb over the hammer' but as I understand the "Murphy law" thing,I will see if I can find a hammerless 360 PD model [ so as to have my cake and eat it too].
I have had 2 S&W 640-1's but they were too heavy [ still have a Ruger SP101 that is the same ] for pocket as a BUG.
And I wont try .357's in the 360 as I am too old and I like my hands to keep working.
Good luck in finding your solutions.
BUT get a lot of input from the wife,if she is the primary CCW of that snub.
