Years ago I sold my 649 .38 Special because I just had to have a .357 Magnum version. I carried .38 Special +p ammo in my new gun but I always wondered how it would shoot with full power .357 Magnums.

I was also concerned with how this gun/hot ammo combination would work out if I was unable to use my right hand and had to shoot left-handed.

This video answered both of my questions.

I try to shoot with my weak hand at least once a month.

I did not try this experiment with my Model 340 PD.
