I have a nice 1911 and stock I can split a card with. I was looking to get into 3 gun and decided to put a mini red dot on it. Now I'm having trouble hitting bullseye. I pretty sure it's lined up correctly but I don't know how to or what to slight the dot with. Do I align it with the front dot, the rear sight, or just use the dot plain. Before you ask I only put the red dot on for quicker acquisitions and follow up shots.
