Trigger Extension

[Hagen]

I had a friend ask about a trigger extension for a rifle that his handicapped friend wants to shoot. I was thinking something like a hammer spur similar to the kind used on a NEF singleshot when a scope is used. Does anyone know of anything that might be available?

 What kind of disability does he have? Could he use something like the winter trigger the milatary used on garands and such?
What kind of gun is he using?
