The 5.5lb V1 LEM that Wolverine sells in their P2000's is the good LEM.
Basically you get a long VERY light takeup then a crisp Single Action like pull. When you release the trigger after a shot, feel the link reengage and you can fire again without releasing trigger completely. It has a long reset similar to that on a Browning Hipower.
Another similar trigger would be the long single action pull on a Walther P99 after racking the slide and not decocking...however the P99 'locks' into SA mode past a certain point whereas the LEM doesn't.
I love single action guns and the light LEM feels like a SA to me, just with a bit more takeup.
