There is a new LC9 and LC380 trigger kit available. The maker is Saints Arms, and the kit is sold through eBay. The kit is two pieces, a new hammer and a new trigger bar. It is a well made kit and the parts are accurately CNC machined and heat treated. I made an install video and a short results video, on the kit. The kit sells on eBay for only $35, which is a bargain. The results is it shortens the pull a little over 1/4 inch and moves the trigger break point forward the similar amount.
