Huh? That is silly.
Many autos don’t require that much grip strength.

Your right. They don't. Most people who haven't used one in 30 years need the muscle memory for a fine motor skill, in order to maintain a consistently hard grip, especially during a double tap. Most people tend to shift or change their grip in response to recoil. That affects accuracy and can cause a semi auto to jamb. I own many Glocks. Outstanding pistols. However, If you want one to malfunction while firing, all you need is a weak or shifting grip between shots.
