Arcade game, not gunsmoke?

Question

Old arcade game, not gunsmoke?
Does anyone remember this old arcade game, which is like gunsmoke, because it's a scrolling shooter set in the wild west, but it is not an overhead shooter, and this game was made far later than gunsmoke so the graphics were quite good. You shot bullets at people on the ground and people on the balconies, so you had two guns; one shooting directly ahead of you, and another shooting at a 45 degree angle to get the people on the balconies. It was a side scrolling shootem up. What was it, I wanna play!
