I recently bought a browning high power mk3 - serial number indicates it was built in 1992. The frame seems to be forged instead of cast. Is it ok to shoot 9mm +p ?

Welcome to the world of the timeless Hi- Power!

I have fired limited amounts of plus P thru my Mark III with no issues. I don't think it's an issue with the Mark III but I have read the use of such is ill advised in the older Hi- Powers. Others on here are much more knowledgeable and perhaps they will weigh in.

There is a good article about this topic here:

FWIW, I try to avoid shooting +P in my HP's. If I feel the need to shoot +P I have other pistols that will probably handle it better in the long run. If you want to shoot +P, it is generally suggested that you at least use a 18.5lb recoil spring.

Flip it upside down and look at the butt. If the butt of the frame (by the mag well) has grooves it is cast. A few cast frames did not get the grooves but the vast majority did.

Any Hi Power is safe to shoot +P............but you'll need to replace the recoil spring more often or better yet get an extra power Wolff spring set.

Mine does not have the grooves. I know it was made in 1992 by the serial number.
