  Product Details

Lem Kit Includes

Each LEM kit comes complete with the following LEM parts:

  • Hammer
  • Cocking piece
  • Hammer rebound spring
  • Light trigger return spring
  • Heavy trigger return spring
  • Hammer spring (long) for USP, USPC & HK45
  • Hammer spring (short) for the HK45C
  • Sear
  • Hammer Axle (solid)

Please note: That any pre-1995 production USP Variants will also need part number 219442 & 209266 (below).

USP LEM & HK45 trigger pull weights quick guide:

  • Use the trigger return spring that may be in any newer production HK pistol or HK part # 209266 (black colored, thinner trigger return spring) for light LEM trigger pull, approximately 4-5 lbs.

  • Use the square spring shaped trigger return spring in the kit for the heavier LEM trigger pull, approximately 7-8 lbs.

    Developed especially for a U.S. government agency, the Law Enforcement Modification (or LEM for short), is a unique trigger mechanism created specifically to improve the trigger performance and reduce the weight of the Double-Action Only (DAO) trigger pull in the P2000SK, P2000, USP, USP Compact, HK 45, and HK 45 Compact pistols. With this mechanism, HK pistols can be fired like a standard DAO semi-automatic pistol where every round is fired by simply pulling the trigger fully rearward with the hammer starting at the forward rest position. The design of the propriety HK LEM system allows the weight of the DAO trigger pull to be reduced to a smooth and constant 7.5 - 8.5 pounds because the two-part hammer is pre-cocked every time the slide moves rearward. Or a smooth 4.5- 5.5 pounds if the operator opts for the lighter trigger pull configuration.

    Please note: The LEM kit will not work in the P2000, P2000SK, P30 models & Mark23's.

    "Not for older USP"

    Joseph Kautz on 5/22/2012 7:00:02 AM

    Stars Rating:


    Comments and Suggestions: My older USP9 built in 1995 wasn't compatible with this kit. Sent the gun to HK for upgrades and the LEM trigger now works fine. Can't fault the kit or HK Parts.net. I should have looked into it further before ordering. I like the trigger and am overall satisfied.


    "LEM Univeral kit installed in '94 USP 40"

    Mark S. on 5/12/2012 8:47:39 PM

    Comments and Suggestions: A couple of things to note. This kit will work with a '94 USP (and perhaps a '93) however, it simply wont be a "drop in" conversion. The newer hammer axle wont fit the old style slot. Material has to be removed (ploymer from the frame) to fit this part as well as some polymer removal behind the trigger action bar to enable the proper reset (Dremel). These are the major mods. In addition to this LEM kit you will need the new style hammer strut part #214819, two piece catch and control latch. The ... More details


    "LEM trigger install"

    Peter Tanner on 5/11/2012 8:54:25 AM

    Comments and Suggestions: Easy to install takes about 30 minutes, but you have to watch the youtube video, this kit does not have installation instructions. High quality as with everything I have purchased from HK parts..


    "Lem trigger upgrade"

    Comments and Suggestions: Wow the s/a trigger pull is smooth and d/a is a great improvement in accuracy.

    Comments and Suggestions: The kit was nice except there were no directions. It would have been nice if a picture of the parts in detail was included for proper orientation.


    "Sweet"

    Comments and Suggestions: Great kit with all parts included to make any changes to your V1 to LEM conversion.


    "Great trigger"

    Donald Merchant on 3/1/2012 9:55:55 AM

    Stars Rating:


    Comments and Suggestions: Great trigger! Note that if your HK is pre 2005 your existing catch won't work and the hammer will contact the firing pin if bumped. Travis at HK (706)568-1906 sent me the correct catch at no charge. They stopped including the catch in the kit because most people had newer guns and did not need it.


    "Lem Parts kit HK 45C"

    Comments and Suggestions: Parts kit worked great. Everything you need to make the switch. It took about a half hour while making dinner to install. Only wish it had some instructions included but these can be found online.


    "Great service"

    walter b kulecz on 1/27/2012 10:26:57 AM

    Stars Rating:


    Comments and Suggestions: Great service, but they forgot to mention it won't work with the "older" USP models with the one-piece catch. They were very efficient at canceling my order when I learned this shortly after placing it. It'd be nice is they mentioned this under the "more details" section. I'm disappointed, but satisfied and won't hesitate to use hkparts.net next time I need HK parts.


    "LEM kit- Awesome"

    Mike W on 1/25/2012 7:12:13 AM

    Comments and Suggestions: Items shipped fast. Easy install, except for the TRS, so I stuck with the original. Note: If you want to retain the safety with the LEM upgrade, you do not need the variant 5 tube, but you will want the variant 5/6 detent plate.
