HK45C Light LEM kit test fire results
I'm a fan of the HK45 and 45C. I've always ran them single action cocked and locked but after following reading Vicker's and Hackathorn's interview on the pistol I decided to give the LEM a try in these guns.
I got one of the two kits in yesterday from HKparts and installed in the 45C. I took it out for a run today and this was the first five rounds fired from the gun, offhand, at seven yards. Ammunition was American Eagle 230 ball.

I won't be going back to the previous configuration.
In the past I've ran my USP45C back and forth on the LEM configuration. I've always been lukewarm on the system but recently have grown to love it. I set up a friend's P30 with the lighter configuration and that gun is a 9mm dream.
This group pictured is also a much tighter group than I've ever shot with the 45C previously single action. The LEM seems lighter and crisper to me and the removal of the thumb safety does wonders for comfort on the thumbs forward shooting style I live by.
I can't wait for Tuesday. That's when the second LEM kit is slated to arrive for the full size pistol.
