It is good that the fracture is not displaced, since it minimizes the risk of lingering tendon or nerve damage. You should talk to your doctor about prognosis, but from what I can see in the radiographs, my money is on you healing pretty well. (Veterinarian, not MD. The hand is more complex than a paw, but the bones heal similarly.)
As others have said, left hand is still good, and there are folks who use their 3rd finger on the trigger, too. Talk to you doctor about the latter, though, because he might not want the concussive force being applied so near the fracture site.
Hope you feel better soon, and that healing is complete.
