Competitor HD: co-witness sights or not?
I recently bought the M&P Competitor HD and mounted the Holosun 507 Comp using a Calculated Kinetics plate. Loving it but only have a few hundred rounds through it so far.
I'm curious, how many of you consider co-witnessing sights a necessity? I keep going back and forth on whether it's beneficial to spend money on new iron sights to achieve a 1/3 co-witness.
