P2000/SK/USPC LEM Trigger Job Part 1

[Big Bore]

I have been asked to repost the thread showing how to do the V2 to V4 and V1 trigger job on the USP/C LEM, P2000 LEM, and P2000SK LEM, so here it is again.

To lighten LEM trigger (USPC, USP, P2K or P2KSK) you need Trigger Rebound Spring and Firing Pin Block Spring to drop the pull to approx. 5 pounds. Price of these parts is 4.50 each, plus shipping.
Firing pin block spring # 214192
Trigger return spring # 214164
These parts are the same parts used in the non-LEM USP and USPC variants.

edited to add updated part numbers
To lighten the LEM pull on the USP/C pistol you will need part numbers
214192 Firing pin block spring USP/C if the gun was made before 2005
209296 firing pin block spring for guns made 2005 or later.
209266 Trigger return spring

According to HK, the following is needed to lighten the trigger pull on the P2000. You will need part numbers:
209296 Firing pin block spring
209266 Trigger return spring
These parts should eliminate the sluggish trigger return some have reported when releasing the trigger slowly but will also make the trigger pull slightly heavier.

However, note that this trigger job was done on the P2K/SK using the first part numbers listed in this post. That pistol is either an AD or an AE (03 or 04) so when doing the LEM trigger job on a pre-05 use the first part numbers listed originally, but if 05 (AF) or later use the new part numbers.

I think this should be a sticky.

Mr BigBore,

EXCELLENT post! More explanative than the Armorer's Manual!

I have a Compact .45 with the LEM trigger. Tommy Thacker did the trigger job on that, and he did a whale of a job - it's slicker than grease on glass. But would it be possible for you to post the same type of trigger job explanation, WITH PICTURES (I'm a picture lovin' kind of guy - I need to see what I'm yanking and banking on) for the LEM Compact .40 and .45 series?

Thanks again for a super post.

Mike

It would be almost the same for the USP/C LEM as it would be for the P2K/SK. The only real difference would be the lack of the right side slide release. Honestly, I don't think the differences would be worth the effort nor do I own a USP/C in LEM in which to convert. As much as the variant change helped the P2K/SK LEM I still do not like the LEM trigger as much as I do the normal V1 (SA/DA safe/decock) of the USP/C variety.
