The HK Universal LEM Kit for HK45 & USP Full Size pistols lets you customize your H&K trigger pull to suit your shooting style and preferences. LEM—Lightened Enhanced Manifold—conversion is a popular upgrade among HK shooters who want a crisper, more predictable trigger break. This genuine H&K parts kit includes everything needed to make the swap on qualifying pistols, though exact pull weight outcomes depend on which trigger return spring you pair it with.
The kit assumes your firearm already has a V1 trigger group installed. It ships with two hammer springs: a longer spring for USP/USP Compact and HK45 models, and a shorter spring for HK45 Compact. Trigger pull weight varies based on your setup—install the existing trigger return spring from your gun and you're looking at 4–5 lbs; use the trigger return spring included in this kit and you'll get closer to 7 lbs. If you own a USP model manufactured before 2005, you'll need to source a separate trigger rebound spring (H&K part 209266) to complete the conversion.
This is genuine H&K hardware, not aftermarket, so you're getting the fit and reliability H&K shooters expect. Whether you're fine-tuning a competition pistol, upgrading a carry gun, or just want a lighter, faster reset on your duty weapon, this kit gives you control over how your trigger performs.

Yes. The kit includes a shorter hammer spring designed specifically for HK45 Compact models. All HK45 and HK45 Compact variants are compatible.
Pull weight depends on which trigger return spring you use. If you install the trigger return spring already in your firearm, you'll get 4–5 lbs. If you use the trigger return spring included in this kit, you'll get 7 lbs. Make sure your firearm has a V1 trigger group before starting the conversion.
The kit will work, but you'll need to purchase a separate trigger rebound spring (H&K part 209266) to complete the conversion on pre-2005 USP models.
The kit includes two hammer springs—a longer spring for full-size USP and HK45 models, and a shorter spring for HK45 Compact—plus all other parts necessary to complete the LEM conversion. You do not need to purchase additional springs unless your firearm is a pre-2005 USP model (which requires a separate trigger rebound spring).
