    My stock G20 shoots a little high at 50ft. The rear site is designated with a big line with a smaller line over it. Is this standard? Happy with the grouping- just have to aim well under target which leaves additional room for error. Many thanx

    Yep, you have the correct sight. You might find the following information useful

    It is our experience the following work best in most cases:
    +0 (6.5) works best on 9/40/357 guns except the 26,27,33
    +1 (6.9) works best with 10/45 guns and the 26,27,33

    Glock Number to Aftermarket Number Chart:
    Glock Factory 6.1 = -1 Aftermarket
    Glock Factory 6.5 = +0 Aftermarket
    Glock Factory 6.9 = +1 Aftermarket
    Glock Factory 7.3 = +2 Aftermarket
    -1 (6.1) and +2 (7.3) primarily used for sight adjustment.

    Sight Adjustment:
    Adjust the rear sight in the same direction you want the bullet impact to move.
    Each sight height will result in a 2"-3” change of impact @ 25 yards.
    Impact is low, raise rear sight.
    Impact is high, lower rear sight.
