LEM Question

Discussion in 'Heckler & Koch Forum' started by HOTHEAD, Oct 8, 2012.

  1. After reading another thread, I realized that I was unclear on part of the LEM system. I currently own a P2000sk, but it is the V3 DA/SA model.

    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?:wow: 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?

  4. The LEM keeps things almost dirt simple & fool proof for most. No way to manipulate the hammer as with your DA/SA gun.
  5. I came here to reply.

    I'm leaving more learned.

    Thanks barth.
  6. LEM is a great, safe, carry trigger. Between the long consistent pull and hammer for safe reholstering it doesn't get much safer than that. Not so much fun at the range though for just pure accuracy work, but it's not horrible either. My problem is I don't shoot it enough.
  7. here is a video i did explaining the lem trigger. is it an accurate trigger system, you have to train.
