Beretta 92A1 Trigger Upgrade

Looking for opinions and/or experience on upgrading the trigger for the 92. Currently it’s sitting at 6 1/2 pounds with a lot of over travel and reset travel. Langdon Tactical sells a trigger in a bag or should I go with the 92X upgrade?
  Trying to find an already built 92 for service pistol isn’t panning out to well so I’m just looking for a little upgrade to what I already have.

Get a Extreme Engineering hammer and sear from KC Langdon I got was not a bullseye quality trigger

My experience with the Langdon kit was excellent.  I put one in my Sams 92 that I had used as a ball gun.  I have his scope mount on it so I could use it as a CF gun, but the trigger pull was too high.  I bought the LTT kit that was NP3 coated so that I could shoot it while I was polishing/honing/etc and not get the parts mixed together.  

I installed it and it was just below 3 pounds and smooth.  To get it to make 4lbs for a ball gun, I would need to swap back in heavier trigger return/FPS/sear springs, but this will be used as a Centerfire gun, so I likely wont bother.  

Just wanted to give you another view on Langdon stuff.
