The Scarlet Gun — J.R. Roberts

Lots of boys dream about being gunfighters, but when the kid brother of a pretty Irish woman picks up his six-shooter in earnest, Clint Adams is forced to get involved.

The Gunsmith is asked to find the boy and convince him to give himself up. But before he can do that, Clint meets an incredibly beautiful young woman named Scarlet who is gunning for a rancher the kid has been hired to protect. Now, the Gunsmith's good deed has drawn him into a dangerous crossfire -- one from which he'll be lucky to get out alive!
