Got a new revolver!!!

[ldp4570]

Well I don't think I'm as smart as I thought I was. I've been seaching ever since I posted and can find only +P in post 72 guns. Don't know where I got the other infromation but have always remembered it that way. Also my pistol dates to 1963-64 instead of 67, so I didn't remember anything right. Guess I should do a little research instead of remembering.
Does anyone know what the triangle with the p in it means?

Those are Colt's proof marks. Not marks for +P ratings.
