The OP owns a 38 and has said he's comfortable shooting it, despite his medical condition. He says he wants to stock up on ammo for self defense.

I suppose if you never trained it would.
Tomorrow is the most important thing in life. Comes into us at midnight very clean. It's perfect when it arrives and it puts itself in our hands. It hopes we've learned something from yesterday.
