Yes, IMHO it is my rated for +P...

All of the "numbered model K-frames .38s" are rated for +P...

However, I would not make a regular practice of it because all of the K-frames are still afflicted by the barrel design flaw where the bottom of the forcing cone is flattened, and does not have the strength of a perfect circle.

It's not that the .38's have the same problem that the .357 Magnums have with the barrel design and fast 125-gr. magnum loads, but, knowing that it exists for hot loads, it might be smart to "be kind to the gun" and limit the majority of your shooting to 158-gr. bullets with lower pressures. O

To my understanding, all of the K-frame "service revolvers" were originally designed to use, and have "point of impact," using the 158-gr. .38 bullets. The extra weight of the bullet slows the projectile down, reduces pressure, and eliminates the forcing cone concern.

Also, the 158-gr. bullets have an impressive downrange wallop...!
