In reading the other post, I realized that I had never thought about dropping the hammer after chambering a round on the LEM model. With the V3 I have the decocker, but what do you folks with the LEM do? Do you have to pull the trigger and let the hammer down with your thumb? I realize there is a drop safety, but does the hammer sit all the way down?

Just realized I had never thought about this.

The HK LEM is DAO - sort of.
There are two hammers.
The internal hammer gets cocked with the slide being drawn back and stays cocked.
The external bobbed hammer returns to the un-cocked position every time.
Hence no hammer drop safety.

Now if you don't rack the slide, or if the primer doesn't fire after you pull the trigger, and both hammers are down.
Then the trigger drives both hammers for double strike capability.
The double strike is heavy like a traditional DA.

But most of the time, if your ammo fires, the trigger only drives
the second external bobbed hammer with the internal hammer pre-cocked.
First and every shot the same trigger pull.
It's like a long light pre-travel, followed by a predictable and distinct wall and a crisp clean single action like break (LEM Light).

LEM generally comes in heavy, medium and light pulls depending on
the springs used.

My P30 40 LEM V1 light reminds me of my G27 with a OEM ''-", or Ghost 3.5 drop in, connector with more pre-travel.

Here are examples of HK P30 LEM options with the part numbers.

Does that explanation make sense?
