Hk LEM trigger experience?

I picked up a P30sk LEM a while back and really liked the trigger. Ordered a kit from hkparts to convert a USP45 to a LEM and did it today. The trigger for normal use feels pretty good and is about what I was hoping for. I don’t have a trigger gauge, but the DA “second strike” on the USP is very heavy. Subjectively it feels probably twice what it is on the P30sk annd is definitely heavier than the DA was on the USP before the change. Anyone with a LEM USP that can tell me if that seems normal? I’ve got an HK45c I was contemplating converting but maybe I’ll wait til I get this one to the range.

Yes, the double action on an LEM where you have to recock the hammer feels like a finger breaker. You can use it if you have a light strike, but you're just better off racking the slide and going back to a cocked hammer.

I did the full kit with square spring, which is supposed to be the heavy. For light I was supposed to use the original trigger return spring or the one in my gun. I may swap it for the light one. The trigger as is doesn’t feel that heavy compared to the light Lem in the P30sk. It is just the fully decocked feels like it’s way heavier. If nothing else this seems like it might be a good to buy a trigger gauge.

I also did the match trigger and sear spring. I may swap back out the match trigger for the original. That thing has so little overtravel there’s almost no point.

I’m not sure anyone has a great answer because the “restrike” capability you are talking about isn’t really a feature. I have about seven LEM guns and I can tell you they are all heavy as shit in the scenario you asked about. The real question is how does it feel when used correctly?

I was just worried that it might be indicative of me putting it together wrong. I don’t plan to use it that way I’m used to the basic tap rack bang to fix a fail to fire

I always make sure to use the light trigger return spring, and the light firing pin block safety spring options in my HKs. If you can strip it down and swap the standard sear spring for the nickel plated option, it smooths out the trigger pull a little as well.

If anyone has any factory P239 .357 SIG +1 mag extensions, I need (5) of them. Email in profile thx!

I am not an LEM guy. I just don’t like them, nothing functionally wrong with them. That said I’ve owned P2000’s in both DA/SA and LEM and can confirm the second strike, fully dropped setting on an LEM gun is noticeably heavier then a standard DA/SA gun hammer down.

That said, while I theoretically like the ability to double strike I just can’t see me doing it. I always tap/rack/immediate action and if you do that you will always be in the “LEM” mode.

At the range I’ve used double strikes just to “play” with potentially hard primers but in any kind of real world situation I want that round OUT!!

Make it totally clear to anyone standing at the wrong end that things are going badly for them. If that means sticking all sort of spikes and prongs and blackened bits all over it then so be it. This is not a gun for hanging over the fireplace or sticking in the umbrella stand, it is a gun for going out and making people miserable with." -Douglas Adams

I have a few guns in lite & regular LEM. I like them for CC, dirt simple, very safe.

I’m not so much looking for the light range trigger with them.

What I have done to all my LEM guns is add the Graygun’s parts and most importantly, his flat trigger.

I think flat triggers are mostly overrated. I bought a bunch over the years only to discover that I got basically no practical benefit. On the LEM guns however this was not the case. It made the break happen perfectly at a 90 degree angle and I instantly saw benefit. For example I bought flat faced Glock triggers and beretta triggers and find I might even prefer the older rounded ones.

Try the flat grayguns trigger, totally worth it.

My dream is a CC9 or whatever HK calls it sized gun with LEM trigger mechanism. That would be just about the perfect appendix gun. Oh yea, add paddles too.

While I am not an LEM fan…..I’d be on board for this.
