It is sold for use in any .38 Special revolver.
A 158 grain bullet has been the standard for the .38 Special since it was invented in the late 1800's.
Fixed sight guns are factory sighted with 158 grain bullets at about that velocity and some folks prefer that bullet weight so they can hit what they are shooting at.
Some folks feel a heavy bullet is best for SD because it will give deep penetration, even through heavy winter clothes, even if it doesn't expand much, or at all.
It can be used for SD, hunting small game & varmints, target shooting, or plinking.
