Made in 1961, long before the advent of P+ ammo, of course it's not "rated" for such. It didn't need to be. The 38 ammo of it's day was about the same as what we call "P+" today. I won't regularly shoot P+, but do carry it. I've never seen much sense in shooting expensive ammo to punch a hole in a piece of paper and that goes for airweight 38's up to my Model 28 S&W. I suspect most people "back in the day" practiced with wadcutters and saved the "good stuff" for serious work too. I know that's what "everybody" told me to do when I was getting started. It's worked all these years.
