Picked up and shot my G17.5 with Ameriglo Bold sights last night, shot smaller groups than what I could with my Gen 4 G19 from 15 yards in but about 4 inches low with 115gr S&B at 25 yards. Measured the sights this morning and they are .200 so I emailed Ameriglo who's sending me a .180 (Offered the .180 or .165) for $30 and said if it's still low to send it back to replace it with the .165. Love the trigger and the way it handled overall and will shoot it again after I replace the front sight.
