ditto and definately replace the trigger bar. Had to carry a weapon DA only, for several weeks, not by choice, went to the armourer told him the problem and he changed the trigger bar and some other things and I improved my groups 60% by this I mean I was hitting the paper target not the black with all my shots. Within a week I was shooting 3 " groups at 50 meters. I hated that weapon to my knowledge it was canned. thank god!Practice, practice, practice! Also, you can buy a 3.5 lb trigger bar that that takes 3/8" out of the long pull. It works great.
I traded it for sw3913
I had an LC9 until 6 months ago. You cant just install trigger bar, you have to mod the hammer as well. It cost about 60 but they were out of the parts. I polished everything, removed the mag safety and cleaned up the firing pin block and shortened the safety spring. I could deal with the pull weight but the trigger released much too late. Otherwise it was an excellent gun. Never jammed and just the right size for ccw. I traded it for sw3913
