My first revolver was a 6" 586 in 1983. It was nose heavy IMO, but that said, others enjoy that feel.
I settled on a 4" 586 and couldn't be happier.
You loose a little velocity with a shorter barrel, but it's not enough to work up a sweat over, truth be told. Add to this, the shorter barrel is easier to hold and therefore more accurate in my hands, YMMV.
For carry and home protection, the 4" is more desirable and is a pleasure at the range.
Will the 6" work too - of course.
The L frame is always a good choice, so whatever you decide, you will not be making a mistake.
Let us know what you decide.
BTW, they don't call 'em six-shooters for nothing. I personally can't wrap my mind around 7 & 8 shot revolvers.
