S&W 686 6-shot vs 7-shot
Had one of each. Bought the 6-shooter for IDPA but I really can't justify ANOTHER dedicated competition gun.
Then bought the 7-shooter. OK, can't use it in IDPA, but I have a wonderful older 586 that works just fine.
The 7-shooter just makes sense to me for personal defense, and is a frequent trail gun when I am backpacking where I don't need the .44 Magnum.
Lighter? I can't tell when it's on my belt. Stronger? I don't think it matters with SAAMI-spec loads. If I want to drill for oil with a .357 handgun (and I have no idea WHY I'd do that), I'd get a Ruger, though I had a friend, years ago, who handloaded for his 1960's S&W, and HIS friends said he could dig tunnels through mountains with it.
BTW, I'd like to see proof that any good commercially made modern revolver has any history of failure at the cylinder bolt stop when used with SAAMI-spec loads over a long time.
I used to have the S&W N-frame 8-shooter and felt it was a great open-carry backpacking gun. One of my charming children claimed it for himself a couple years back and I haven't seen it since.
Anyway, for my money it's the 7-shooter.
