I got my Hk45ct and fired 200rds today gun functions great feel of the gun great heavy lem not so great. The gun is a v7 and my question is what springs do I need to convert it to the light lem?
The light firing pin block spring block spring may already be in the piston, but it's only $5. You ALSO need the standard V1 hammer spring (mainspring). Part number is in your manual (mine is not handy).

Put the heavy one in and pull the trigger.Why do you need the other V1 hammer spring? In the LEM trigger variant the hammer spring does not affect the trigger pull at all. If you question this take the backstrap off of an unloaded HK45, 45c, or P30, rack the slide, and dry fire it while watching the hammer spring. It does not move until the hammer is released. It doesn't affect your trigger pull at all as the gun is fully cocked when the slide is racked.
I agree. The amount of pressure put on the cocking piece by the hammer strut is greater with heavier spring. That translates into more force needs to overcome that. It's not much but it's different. If it wasn't they wouldn't make different springs.Put the heavy one in and pull the trigger.
Put the light one in and pull the trigger.
Then try and tell me there is no difference, because there is.
It doesn't affect the trigger pull, but it does affect the force required to pull the sear away from the hammer. It's friction, not spring compression.Why do you need the other V1 hammer spring?

This I understand and do agree with. I was under the impression that we were discussing the weight of the LEM take up before the break. My reasoning for assuming this is that even in the 5.5lb LEM kits HK offers a new hammer spring even though the standard DA/SA hammer spring would already be in the gun being converted. Why would they send a new hammer spring if it was not intended to be installed?It doesn't affect the trigger pull, but it does affect the force required to pull the sear away from the hammer.

I tried it. And you are definitely correct. I now have the standard V1 spring in, as with the V1 hammer spring, the trigger break is much smoother. Thanks for the info, and the recommendation.Put the heavy one in and pull the trigger.
