I've looked at the guides for LEM install on HKPro, got everything to look right, and the trigger won't work -- when installed, the gun doesn't seem to cock and once the hammer's back the trigger won't do anything nor will it go forward. I'm pretty much at my limit here... Apparently HK decided one needs six hands and a team of engineers to do anything besides change a RSA on their firearms.
Anybody dealt with HK customer service? I have the 4.1 parts. Any idea what the cost for an install might be? Or is this something a local gunsmith would be able to do?
