I spoke DIRECTLY with S&W customer service about my no dash model 60. They said it is NOT made to handle +P ammo and recommended against using it.
In my mind, doing anything other than following their recommendation means that I only have myself to blame if the gun is damaged by shooting +P...even if it's only a few rounds.
If you feel the risk is worth it then go ahead, but I won't shoot +p out of a revolver that doesn't say +P on the gun.
