I've had a 40 Shield over a year. It arrived at the dealer MA compliant and had a 11 pound trigger pull and I could not keep a tight group (low and right). I put an Apex trigger kit in and the trigger pull fell to 5.75 lbs. All the grit in the trigger disappeared. I now have consistent 2 in. groups out to 25 yards. It has now become my concealed carry of choice. My Sig and Glock just don't hold as well. I also put an Apex trigger kit in every pistol I have if they make one for it.
