Arthritis in my hands is increasingly making it hard to rack the slide.

Are there any slide rack assists that will work for the M9A1?

Something like this one for Glock

If there is, it may only be marketed in europe, so you might have to search.
I can think of other approaches but they would not be as convenient.
This is not a bad idea just for using a weapon wrong hand or with an injured hand in combat.
