The below is from an ongoing post at another forum.
QUOTE]I bought a used S&W 640 marked .38 Spl on the barrel. Inside the cylinder frame opening of my 640,on the bottom visible when cylinder is opened, is stamped, "TESTED FOR +P+". [/QUOTE]
The O/P did not post any photos. Yet a second poster did post the photo below, so if everything is correct there are at least two of these revolvers out there somewhere.
Anyone have any information on these. Yes, I do know that there is no recognized SAAMI specs for +P+ ammo.
