One Handed Gun - J R Roberts - Bog

Palmerville, Wyoming had a good lawman. Marshal Dale Leighton. At least, he was good until he lost an arm in a gunfight. Hearing he was in trouble, Clint Adams, The Gunsmith, rode hard for the town, vowing to help his friend. And help he does, teaching Leighton to use his left hand and training him until the marshal is better with his new gunhand than he ever was with his old. But soon The Gunsmith sees something else... Leighton has turned vicious and uses his deadly new skill even when there's no call to. The Gunsmith has to turn against his old friend to help the town... and one of the first people to get his help is Lisa Lancaster-an inexperienced girl who learns fast.
