HK LEM Trigger Conversion Questions

[Aufdrahtsein]

I currently own an HK USP Fullsize 9mm, and I'm pretty tired of the ridiculous stock trigger-pull, so I was thinking about making the transition over to a LEM style trigger for the shorter return and lighter trigger pull; does anyone have any experience with the LEM Trigger, whether you've installed it or currently use it? I'm not too keen on the anatomy of the pistol, but I'm trying to reduce the trigger pull and the return distance before a second round may be discharged. Suggestions to other possible modifications that ought' to be taken into consideration?

I want a usp 9 real bad.. I'm old school so I like the da/sa with a crisp clean sa break...

They are butter smooth guns...just to rack one is a pleasure

Let me know if you sell yours

I haven't done the conversion from DA/SA to LEM, as I bought a P2000SK with LEM. I did lighten the pull with 3 1/2 pounds and it shoots really nice. Although, there is quite a lot of pull from the LEM. It also isn't as easy to reset the trigger as compared to a Glock. I had a Glock 23 and enjoyed it, but sold it when I picked up the P2000SK. Just took a little getting use to with the P2000SK, but it is a very accurate pistol.

I converted both my USPc and USP to the LEM trigger and really like it a lot.

It is an easy install ( 1st one about an hour, 2nd less then 15 min ) and my kits came with a couple spring options so I could pick my trigger weight.

I also added the extended mag release and that is also a lot better.

I love my pistol ( sorry willerfortheworld! ), but as I'm sure you HK owners and users know, it seems to be a weak point in most HK pistols that the triggers are how they are. The only upgrades that I have currently on my pistol are contrasting tritium night sights and I changed it from a Variant 1 to a Variant 2 ( I'mma lefty ). Hkparts has been good to me, so I might get their conversion kit sometime in the next couple of weeks, but during that time I will be investigating http://www.triggerwork.net/usp.html to look at their options as far as reducing travel and trigger pull. Now, correct me if I'm wrong ( I am more than likely, as I just woke up and I'm out of coffee ), but if I change my HK USP into an LEM configuration, I lose the ability to operate the decocker once I make the switch? That's kind of an integral preference that I would rather not lose, so I might just see about the triggerwork.net website has to offer. Has anyone used their services before?

forgive my ignorance, but what is LEM?

Yes, you remove the decocker as it will be "single-action only" with a long but light initial trigger pull/slack, i.e., "decocked" when not in use. Once you take out the slack, it's quick follow-up shots thereafter.

Converting my V1 to LEM trigger on my USP9 was very easy. I do not think it changed the actual reset distance though.

It does feel more like a striker trigger though since when you are releasing the tension after a shot, it will take you past the reset point rather than stop on it.

I have all my HK's fitted with the LEM trigger. I use the 'light' version, which
is user installable with the swapping of easily available springs.
The stroke is long, but not a problem, the weight is good.
If you look on the pistol training forum you will see some very fast
and accurate shooting with the LEM trigger. If you train with (like any other
gun), then you can be as good as you want to be. Yes, the reset is a little
less defined than a 'springy" glock reset, and a bit longer, but very manageable.

The HK stuff and tests on http://pistol-training.com are very good reading.
Get the LEM and don't look back!

I run LEM on all my HKs cept my P30L. The reset varies gun to gun as each model internals are still different. The reset for the 45 series is pretty short, USP maybe a bit longer and the P30 really long.

So far from the reviews I've been getting, it sounds like it may just be my best option. At the end of the day, all I want is a reduced travel and a reduced trigger pull; as much as I would like to keep my decocker, I suppose I can't argue with the notion that I can just safety the pistol and have a pre-tensioned follow up trigger pull after the initial first shot. The LEM conversion would certainly make my initial shot a little bit more predictable, considering I feel like I'm fighting the spring; every shot after that is beautiful and crisp. Should I take anything else into consideration before making the purchase?

[Massan]

Reduced travel would be SA option as the initial take up of the LEM is still long like a DA, just lighter. The benefits of the LEM is that the pull weight is the same and all you need to do is release the trigger a bit for the reset and your good to go.

You can try swapping your trigger spring for a match one for a lighter pull and keep it cocked and locked if your comfortable with that carry method.

I have 2 LEM set ups. One is a P2000 and the other is a USP Compact. The reset point on the USPc is closer to the release point than on P2000, so they do shoot a bit differently.

Another option is to go with the DA/SA match trigger. The USP Expert comes with it from the factory, and it is smoother shooting in DA than the regular USP.
