Best small platform rd optic. - Aimpoint ACRO P-2 Red Dot Reflex Sight

If you are contemplating a RD optic for a true defensive pistol this should be at the top of your list. Of course you can run it on a PCC or even a good choice for a home defense long gun. Not the least expensive but this is a case where you truly get what you pay for. It is a closed system, which makes it larger than some on the market but the advantages outweigh the drawbacks of perceived "chunkiness." It mounts easily and true requiring little adjustment to sight. Red Dot pick up is incredibly fast. I have one on a FNX45T and one on a H&K VP9L and H&K VP9SK (current EDC). I will likely place one on a FN Reflex for EDC. Aimpoint quality is established as the best and if you are trusting your life to something isn't that what you want?
