My S&W 642 is very light with the aluminum frame.
Now I'm seeing writers like Chuck Hawks literally urging owners to use standard .38 Special ammunition, rather than +P.
I think some folks expect the gun will jump too much, and be hard to keep on target, thereby reducing its effectiveness in an emergency.
I can imagine you would not want to shoot +P all day at the range because of wear and tear on the shooter and the gun.
I'm tempted to practice with standard rounds, and carry +P. And also shoot a small amount of +P at the range to see what it feels like.
Do you think +P is best for ordinary carry? Obviously, it's not like the shocking experience of a .357. I want to follow the herd on this one, and do what is generally accepted.
