Big Man in the Saddle

Surprising western adventure about a Irish immigrant, fresh from the wars but not out of trouble, seeking to make a go of things out west. He also makes a go with a Mexican cutie, and, for most of the story, finds himself tangled up with innocent twins... well, maybe not so innocent. Of course, it's near impossible for him to choose between them. But luckily, that situation resolves itself nicely.
