Cupping the balls 

When someone grips a pistol (typically a magazine fed pistol) incorrectly by putting their non-dominant hand at the bottom of the pistol's grip, typically looks like your non-dominant is cupping a pair of testicles.

He's cupping the balls on that pistol, he has no idea how to hold it properly.

Cupping the balls is not how you hold that.
