Remember, this was posted a long time ago. CDNN had the kits for about a year but they have been sold out now for quite some time.
The take up on the initial shot and break of the trigger is very similar to the SA pull on a standard V1 in SA mode except with the LEM you will see the hammer moving back to full cock as you pull the trigger. There is a little more stacking at the end but not much. I have not noticed it but others have commented that they feel there is a bit more stacking but that would mean that the take up would be lighter than with the SA V1 since they break at about the same pull weight.
