Does anyone know of a slide racking device compatible with the P10C?  I have an elderly student who is having difficulty racking her slide, even using the "push-push" technique, when it's fully closed.

This is not a malfunction, it's purely that she's over 65 with arthritic hands and not a lot of forearm strength, I can rack it easily.  There are devices made for other semiautos to help with racking the slide, but the Pachmyr one specifically says it's not for CZ's but works with other pistols.  I know my SP-01 Tactical slide (and most 75's) have a fairly slim slide that is difficult to grip, but the P10C has a more conventional blocky slide like a Glock.  My wife's VP9 has slight protrusions on the slide to make it easier to rack.

Yeah, I've considered recommending a red dot, because I think it would help with her sight alignment issues (she keeps looking over the rear sight, so she's always got good groups a little bit high on the target at 10'), but I'm hesitant about recommending expensive options.  Just like I think an extended slide stop lever is a good idea on that pistol, having handled hers, and I've looked up how to swap her magazine release for left-handed use but would need to have her let me take the gun home to work on that.
