I am looking for some opinions on night sights for my Gen 3 G27. I am torn between Ameriglo Operator and Ameriglo Pro Operator. I will probably get the green/yellow combo. I am also considering the Meprolight green/yellow specifically for the G26/G27. The gun is my CCW and am thinking of trying it out in a local IDPA match so I am looking for a compromise between day and night conditions.
