Mine doesn't say +P. It was made in 1977. However, they are made the same way now as in 1977. I don't think they case harden the trigger and hammer any more. If a Taurus M85 can handle +P then a Smith and Wesson model 36 can too, it's just that I like the standard pressure rounds. The difference in stopping power are no that significant in a snubby, but I understand wanting the most power you can get.
