I carried +P for SD in my light weight snub Colt(Cobra) years ago as a BUG. All of us in the dept did, we did not use +P for range. I had fired one cylinder through the gun to get the feel. The gun handled them just fine, S&W like any company tries to cover their backside. You have to do the same, decide whether you need them in a SHTF situation or not.
