- In this video I cover the history, features and benefits, as well as answer the most common questions regarding Heckler and Koch's unique LEM trigger system.
I have the LEM trigger on my HK45C and by God it's one of the best triggers I've ever experienced.
I am a former military vet as well, having been trained in 1911's and Berettas. I have since enjoyed both CZ and SIG DA/SA pistols more than the other striker variants. I do like the lighter trigger pull weights of my modified Glocks. But since the triggers are so light (3 to 4 pounds), I'm hesitant to leave a round in the chamber when carrying. I feel safer with a safety or even a heavier DA (less than 8 pounds) in my CZ customs or SIGs with a round in the chamber. If I'm not using my safeties, I carefully lower the hammer by hand and just expect the DA first shot. On my SIGs with decockers, I just use those. Having different pulls is my tradeoff, but I see it as a time issue. If I need to take the shot, I would just deal with the heavier DA. If I had time, I would just thumb the hammer back. I would like to get to a point where I can just draw and be prepared to shoot without the need to remember if I have a safety on or not.
I was surfing the web this morning trying to understand if an LEM would help me or complicate me since most of my firearms are DA/SA, with some striker-fired Glocks and CZs. I came across your video here: www.hkpro.com/threads/langdon-tactical-hk-p30-lem-series-pistol-first-impression-thoughts-and-questions.561006/
This is the best explanation I have seen, and I've been searching the web for months. GREAT JOB!
I'm subscribing now based on this video alone, in the hopes that I learn something else from you. I also don't want to lose track of your excellent explanation.
I did learn something. Thank you. I first got a full size HK45, double/single. Thought it was normal. Recently, I got an HK45c LEM. I'm discovering the difference. And what a difference!
Very well done and informative video. It is so nice to not hear the term, "this little thing" or other variants when so-called experts try to explain something they don't truly understand. It is obvious that you know your business inside and out and can communicate it succinctly. I'm in Greenville and will be having you install the "light" parts on my P2000 LEM as soon as possible.
Glad you enjoyed the video, and I’ll be happy to help with your install. You can reach me via the website for shipping instructions.
thanks! i have totally misunderstood the L.E.M. for years. there is very little info on what is really inside those actions. you have made it very clear.
Thank you for a well organized, well presented orientation on the LEM. Some of that information was new to me. Well done!
Thank you for the details and history of the LEM trigger...great video, I really appreciate the detail and effort in the presentation!
Ronin Cato Thanks. I’ll keep them coming. Check out my other HK reviews.
This is extremely informative. I pick up my newly manufactured P2000 V3 in 4 days. Although I've shot single SA and DA, this perspective gives me a deeper appreciation.
Converted my USP9 to LEM but kept the V1 DA/SA hammer spring and installed the heavy squared off trigger return spring that came with the conversion kit back in 2014 or so and I loved it.
Just recently got a trigger blade with the overtravel stop and the nickel sear spring and installed them and it is _really_ nice now, the stop physically limiting the trigger overtravel makes the overall pull feel lighter but I still have a positive feeling reset because of the heavy return spring.
Certainly not something H&K would advise doing I’m sure, but I like it a lot.
Best LEM explanation I have seen so far. Thank you sir. I have the V7 LEM HK45C and I was shocked how much I love it!
Thanks. Tons of H&K info on the channel.
Thought I had seen all of your videos, but somehow I had missed this one. The irony is we have spoken on the phone on the subject and the possibility of a conversion, albeit unauthorized.
Really enjoyed the history lesson and especially the direct and organized tutorial on the individual parts, their function, and how the systems differ. Very helpful and enlightening!
Love what you do and the way you do it.
Glad it and the others have proved helpful.
Learned some things. Youre doing the lords work. Now that I have my p30 lem I'll definitly be switching my usp also.
I appreciate it.
Love your videos!
Another awesome video James! Would love to attend an armorer class in Oklahoma/ N. TX covering the MP5, USP, P30 models if you are ever this way.
It would be great if RUclips would let you do a complete install video. Next time you offer your usp,p30 armorers course out west, I'll definitely be taking them.
Very cool video... great information. I love the DA/SA on V3 USP 45. still its great to have wealth of information none the less
Thanks for the share!!
It's Friday February, 24th about midnight. In the morning, I will be going to my local gun shop to pick up my new HK usp 9mm v7. This will be my frist usp and I'm so looking forward to it ! Great channel, super helpful 👍
Congrats
Thank you, sir .
I'm fortunate enough to own a HKP30L lem, HKVP9SK, and as of today, a HK USP 9MM V7.
The owner of the gun shop who ordered the USP 9MM for me, told me it is outdated ?
Ha ha ! The gun shop owner reminds me that, God has put a limit on our intelligence but none whatsoever on our stupidity lol The USP 9 v7
Looks and feels magnificent so far..👍
I wish LEM triggers and jet funnel Mag extensions would come standard on USP’s. Lol. Good video.
This trigger design is highly underrated and I wish more manufacturers would innovate with hammer designs like this instead of all just making Glock striker clones. Unfortunately, I think it sells itself very poorly since in a gun shop it functions like any other DAO unless you know how it works and cycle the slide. The know-it-all employees also just treat it like an outdated DAO relic not even worth looking at.
Great information, I'm definitely interested in trying the LEM in one of my HK pistols. Based on everything I think I'm going to get the conversion for my HK45 first. Probably going to send it out for install, so expect an email soon.
I'll be happy to help.
@@teufelshundtactical I have the kit in my cart on HKParts, just waiting for payday.
So it's a DA/SA with an internal hammer that is tripped by the external hammer and sear, and the external hammer is operated by the trigger.....
Neat.
I'd say HK's LEM and Walther's AS are some of the most misunderstood pistol fire control groups out there and I carry both: HK P2000V2 and Walther P99AS.
Agreed, hence me creating this video :)
Question for you.
First, I got a lot out of this video, thank you.
I'm convinced of how good the LEM trigger is. I'm considering getting a H&K USP, and I'd either get it with LEM, or convert it. But because I'm a 1911 guy, and have trained for years to use that thumb safety. Is it possible to have a USP with LEM, and a thumb safety? If so, what's involved in doing so? Thanks again for the great video!
John Kelley Brown It can be done, but completely defeats the point of LEM. The best advice is just learn to let go of that perceived need. It’s not as hard as you think and I had to do it too.
Great video and info, was wondering if a USP with a factory LEM would ever have the White SF tick on the frame. I’ve been looking around and not sure if someone had converted it or it was original.
Thanks. Yes, it should.
Awesome thanks for the reply on an old video!
I'm on the fence between LEM and DA/SA. Looking at the P30. Still haven't completely decided, but this video is extremely helpful. I carry AIWB and I'm just finding myself extremely uncomfortable holstering striker pistols with one in the chamber. That's why I'm switching to a hammer fired pistol. I was originally all in on DA/SA, but the LEM is starting to creep into the discussion.
I highly recommend you take one for a “test drive” before buying to make sure you prefer LEM.
@@teufelshundtactical thanks for the reply. That's the idea, just tough to find somebody in the area with a range that rents one out. I've dry fired them though
More USP content sir
I had a chance to mess around with the HK before I left INS. After shooting the Beretta 96 for years, with its ridiculously long double action only trigger, I had no idea what trigger reset was and shot the HK poorly. As a private citizen now I have a stack of HK handguns, some with LEMs that you installed. Is there anyway to get the pull below 5 pounds? Thanks for doing these videos.
Using the light LEM trigger return spring and light firing pin block spring will reduce the trigger pull.
Wasn't there a p30 LEM variant that had the decocker on it for German use? I think it was on Wikipedia
Yes, both the P2000 and P30 had that variant and I’ll be covering it in an upcoming video.
Can you use USP LE sear, cocking piece (goes in the hammer), cocking spring, and hammer in a regular new USP V1 frame to get LEM functionality?
The receivers on the USP and HK45 series are modular and you can convert any of them to LEM light or heavy with the LEM conversion kit, replacing the original DA/SA configuration. I show this in the video.
I have always felt H&K had weak resets. Don’t force my finger forward. Perhaps I try the heavy trigger return spring
I think you just got used to Glocks having that extremely strong reset. No other pistol that I know of has the reset Glocks has.
Question for you. Is it possible to do an SAO conversion on a USP?
Yes. You can carry the USP series cocked and locked, like a 1911
What is the reliability benefit between hammer vs striker fired?
Striker-fired pistols do not have second strike capability while hammer fired pistols do. One of the main reasons I'm still sticking to hammer fired like my USP-SD.
Isn’t there a Medium LEM as well?
I heard that The LEM models don’t do as well in torture tests...Do you know if this is true?
I don’t follow social media influencers who do “torture tests” as a way to sensationalize their audience. But as far as whether LEM vs DA/SA has proven to be any less reliable through actual use by commercial or LE customers, I have not seen any issue. In fact the only part that I have seen break more than once in all my years of working on H&Ks is the sear spring and that is the same part on the USP through P30 series. These are incredibly well built and reliable pistols regardless of the variant you get.
@@teufelshundtactical Thank you for the response. I have a P30sk, P30 and a P30L all in the V1 light LEM. I installed the grayguns short reset trigger system in all of them. I also own a USP Compact and full size. I love and cherish all of them. Thank you for sharing your knowledge. I love H&K.
@@teufelshundtactical What is your preferred carry weapon if you are just running some errands around town?
@@loveyourfreedom3903 The P7M8 has been my primary carry since 1997. I rotate in a VP9 and VP9SK often.
@@teufelshundtactical that is great! Excellent choices in my opinion. I carry the p30sk during the day and at night the P30.
What parts break on an LEM setup?
If properly installed, you should not have any issues. The only trend issue I have seen break on the current hammer fired pistols from H&K (and this is very rare) is the sear spring.
@@teufelshundtactical you the man sir. I just bought my first v1 P30L LEM. I am use to glocks and cocked and locked H&k USP series guns. Hopefully it’s a nice mix between them
My LEM trigger clicks at the wall when it is pulled before it breaks. Is that normal?
I don’t recall that. The click should be heard at reset.
@@teufelshundtactical it feels like the trigger has to move a minuscule amount more before hitting the wall (almost like a false wall).
That’s the clicking sound I was hearing. It was converted from V3 to light LEM.
Can you do a video on V4.1 LEM?
Are you Charlie Sheen’s long lost brother?
Good information, but it is difficult to hear what is being said.
Why is a hammer gun more reliable than a striker fire?
Striker pistols have a greater chance of dirt/debris interfering with the operation of the striker.
Anyone know where I can send a vp9 slide for rmr cutting?
