Don't worry about the sights, They only hold you back when trying to learn how to use the red dot. To use a red dot you need to do target focus, anything else slows you down. You need to dry fire your draw for 10 minutes a day for about three weeks. The first week draw and find the dot and reholster, then repeat over and over. The second week draw and find the dot and reholster for 5 minutes. the next 5 minutes draw move gun to weak hand find the dot, repeat over and over. No trigger pull just find the dot. The third week draw and find the dot two trigger pulls mag change, find the dot two trigger pulls. repeat for 10 minutes.
