Installed apex DCAEK. Factory trigger was at 6.5lbs. Went down to 4.5lbs. with a short/positive reset.

Added Truglo TFO night sights ( xd-hs2000.com as stated by someone earlier) and polished the feed ramp.

Shield shoots like a champ! I might get brave and try stippling the grip, but I need to practice on some pmags first, lol.
