H&K LEM trigger system broken down!

[@jamesallen5591]

This is the best explanation/description of the LEM trigger that I have ever seen. Good job!

[@maximusjoseppi5904]

James Allen thank you sir, glad you enjoyed it

[@jamesallen5591]

Miximus Joseppi I am old, and I learned to shoot at a young age with a Colt 1911. I then learned to shoot and operate DA/SA pistols. Currently, I own a CZ 75B SA. I love it for plinking and range shooting, but not for home defense. I am not comfortable with it being in condition one all the time, nor am I comfortable with lowering the hammer on a loaded chamber in the house. Doing so at the range is no big deal, but at home? I've never experienced an AD, and I'd like to maintain that perfect record. So I started researching pistols, and came across the HK P30, and was confused by the LEM trigger. I was thinking that it served no useful purpose over the DA/SA version, except for carry. Your video has changed my mind. This is a new beast, and may be my best solution. Edit: I'm not wedded to the 9mm platform. I love the .45 ACP and that HK45 looks sweet!

[@jermainemjoiner]

Exactly...

[@FrontierSetter]

I agree wholeheartedly about the aspect of having an external hammer for safety, which is why I also carry a USPc (even though mine is DA/SA). My P30SK also comes with this LEM trigger, it's very nice. I love it when people say HK triggers feel like a staple gun because they've read one comment on the internet and regurgitate it on every video, when in fact all they've ever shot is Glocks and have never touched any other platform. But I digress... great video, solid explanation.

[@maximusjoseppi5904]

haha ya... i mean, without upgrading this trigger system at all, its phenomenal. the USP series is even better if you get the match upgrade. the guns are just tanks.. thank you for the comment, glad you enjoyed the video!

[@FrontierSetter]

You do the youtube gun community a service by providing accurate information. A lot of people are mislead or just don't know shit. You're to the point and honest. I don't know why, by my first shot accuracy is better in DA than in SA, but that's most likely because I've just trained that way. Looking forward to the next video man!

[@maximusjoseppi5904]

thank you sir, very kind. i just do it for fun and glad some people enjoy it! im not the best with DA pulls, ive been spoiled forever by LEM, cocked and locked or striker guns haha, i applaud anyone who is though. thats lots of consistent training, good work.

[@FrontierSetter]

Looks like an Inforce APLc (AC-05-1) to me. Compact since the front of the light does not protude. But I'm sure Maximus will correct me if I'm wrong.

[@anthonycesario4056]

I see said the blind man as he picked up the hammer and saw. Good explanation. Thank you.

[@jdglock9114]

Just watched this again. Your message was well delivered.

[@TheBoxingCannabyte]

Just got a v2 p2000. Can't wait to finish paying it off! Will be 2nd HK

[@andrewd4406]

Have the P2000 in heavy LEM. Hated it at first , now would never trade it anything and I'm buying all HKs in LEM variant

[@douglasmcnay644]

I think that calling it single action/double action is a perfect description of how it works.

[@gc5Hayward]

Excellent explanation ; I'm considering having my hk45 converted. Rock on!

[@danpeaslee6786]

Still a cool system. Good to learn about that internal hammer.

[@jdglock9114]

Was blessed to shoot an LEM a guy had at the range. OMGoodness! I nickname it a 1-1/2 action since the hammer stages “halfway” leaving only a short travel rearward before its release forward to fore the round. I want to try it again.

[@theseasonedveteran]

Well done explaining this! Been trying to understand this trigger system and finally got it thanks to you.

[@johnnybeanz1296]

Excellent vid. I couldn’t figure out the differences between the variants and could not find any vids adequately explaining them. I contacted hk customer service and told them what I wanted and they told me which variant I wanted. I got the 45c variant 7. I like it a lot but the microscopic reset takes some getting used to.

[@Integr8d]

That’s all I was looking for in the explanation: 2 springs… You don’t even have to cycle the slide. Just pull the trigger enough to expose the hammer (in ‘double action’) and then pull the hammer back with your other hand till it locks the main spring.

[@johnchristopher20]

This is the hammer version of the Walther P99 AS striker system; long, light pull unless you either need a double strike, or you deliberately decock it by pushing the button. Both have light single action pulls, second strike capability, and are generally misunderstood by everyone.

[@MADZULU27]

I'm surprised no one has said anything about you using P series variants for an HK45. They're different. The HK45 variants are basically the same as the USP series guns.

[@stevenkennedy4130]

Um...wow!

[@Jeff-sc1df]

Thanks man, Could not find all this info in one place. Cheers.

[@Antonio-ye1jv]

Good explanation. I understand somewhat better now. Have to watch many more times. 🤦‍♂️ However can u do detail explanation on a lem v7 variant?? Any model will do. I want purchase a usp to go with my p30 da/sa and 3 strikers. Tks .

[@anthonycesario4056]

Thank you. Very good explanation.

[@evanfrost2500]

Sorry I have to ask cause I'm still confused. I understand the whole concept and everything, but I went to buy a hk p30 v1 9mm at a gun shop and they asked me do I want the DA/SA or the DAO. I thought with the LEM v1 version that there was only one. For your hk 40, what would they call it, DA/SA or DAO cause I love how yours is.

[@bradskis81]

It's really neither.. it's more of a combination of DA and SA. You have to think of the hammer system as two different systems working together. There is a cocking piece, a little round mechanism that nests inside the hammer. That interacts with the hammer spring only. The sear holds that piece back in a cocked position, compressing the hammer spring. Once cocked, it holds there just like a striker fired pistol. However, since that cocking piece is independent of the hammer, the hammer is allowed to go forward, leaving the cocking piece behind. When you pull the trigger all the way back, the sear releases the cocking piece, which then that forces the hammer forward. When the slide cycles, it cocks the cocking piece again, and allows the hammer to do it's independent thing again. Any LEM version is different than a strict DA only, SA only, or DA/SA in the traditional sense.

[@danpeaslee6786]

The one reviewed in this vid is DAO. I’m late to the game… all you need do is ask for the LEM model. If they still ask is you want DA/SA or DAO then either ask for the owner or go elsewhere. Cheers.

[@samkun3297]

maximus what name that cerakote goes by it looks amazing

[@nobodysreview6137]

It is a double action gun but it's design lets you control the trigger in a single action manner. Glock is technicly a double action pistol btw the LEM is very Glock like in Lem mode. No safty or decocker.

[@maximusjoseppi5904]

no, its literally nothing like a glock trigger haha. a glock trigger simply pulls the striker back a little bit as you pull the trigger, an LEM is fully cocked and gives you a single action pull with a large amount of takeup. theres nothing similar about the two trigger systems.

[@audacityofthemind8348]

I can tell that’s a US made HK 45 cause there are no markings to indicate date of production on left face of the gun

[@youvandal411vm]

Why the junk light?

[@fearnonebutone4977]

Is the LEM the same in the HK45, as the HK P30, as the HK p2000, etc?

[@maximusjoseppi5904]

They function the same but the quality of the trigger is much different. The stock hk45 lem is significantly better than the stock p30 lem

[@hillshepherd9444]

How do you get the LEM trigger with the least amount of poundage pull?

[@CT-Woods]

Dude, that IS the least amount of trigger pull.. anymore and the dog go breeze will pull it xD

[@david029014]

Is it true with lem you lose decocker?

[@maximusjoseppi5904]

watch the video you are commenting on.

[@sxleong]

It's single-and-a-half action trigger

Thank you! Excellent explanation.
