[Aguila Blanca]

Have you tried Shooting left-handed? Does the right hand have enough strength and mobility to serve as the support hand rather than the firing hand?

I second the suggestion for physical therapy. Several years ago I had surgery on my left hand to relieve DuPuytran's (sp?) Contractures (a.k.a. 'Claw hand" or "Viking's disease"). The surgery involves opening up the palm of the hand and slicing and dicing the fascia surrounding the tendons that operate the fingers. The hand was completely useless after the surgery, but physical therapy brought it back.
