Mas, my wife has advanced arthritis which has taken much of the strength from her hands. She can still shoot well and load and insert a new mag. But pulling the slide is next to impossible. The question is, what do you think of the charging or cocking handles that evidently screw mount on the rear of the slide? One's got a loop on the end that looks functional and solid. Don't know if it's plastic or metal. Thanks for your time.
