Special LeM Considerations
HK Lock-Out Device - With the exception of some special order production runs, all new
USP Series pistols assembled at the factory after October 1999 are fitted with HK’s Lock-
Out Device, an internal safety lock located within the lanyard loop insert found in the heel
of frame and described in detail in Section 8.
On USP pistols that have LEM parts installed, the HK Lock-Out Device cannot be engaged
(locked) if the LEM cocking piece is cocked and the hammer spring is compressed.
To engage the HK Lock-Out Device on pistols fitted with LEM parts the pressure stored
in the hammer spring must first be released. You must CLeAr the pistol, ensure that it
is unloaded and safe and dry fire the pistol once to release the cocking piece and the
tension on the hammer spring before you can engage the HK Lock-Out Device.
Long Term Pistol Storage
Anytime the slide is moved fully rearward on the USP Pistol fitted with LEM parts the
hammer spring is compressed and held in that position until the cocking piece is released
by pulling the trigger on the pistol. Therefore for long-term storage (more than 1 year)
it is suggested that the pistol first be CLeAreD and made safe then pointed in a safe
direction and dry fired to release pressure on the hammer spring to maintain its life span.
Firing
When pulling the trigger rearward you will first feel a relatively long length of free travel
(slack) and then a second stage of heavier but consistent pull that actually releases the
hammer and fires the pistol.
In addition to providing an improved DAO trigger pull, the LEM also provides a very short
trigger reset distance to enhance the speed of multiple or follow-up shots.
WArNiNG: Do not place your finger on the trigger or within the trigger guard until
you have made a conscious decision to fire the pistol.

UNLOADiNG THe PiSTOL
To unload the pistol, follow the “Clearing” procedure on page 9.
If the pistol fails to fire, clear and disassemble it and check for:
1. Obstructions in the chamber, bore or frame. Remove obstructions.
2. Bad ammunition. Try new am mu ni tion.
3. Unserviceable magazine. Replace magazine.
4. Fouling or lack of lubrication. Clean and lu bricate the pistol in ac cor dance with the
instructions con tained within this manual.
5. Evidence of severely worn or broken parts. Contact your authorized HK dealer or
unit armorer.
If your pistol still fails to operate correctly, contact your unit armorer, authorized HK
dealer, or Heckler & Koch’s Customer Service Department for guid ance.
WArNiNG: if a cartridge is assembled without powder (a fault of the manufacturing
process), the primer alone has enough power to propel the bullet into the bore. A
bullet lodged in the bore may cause dam age to the barrel and/or pistol if another car-
tridge is fired and could cause personal injury or even death. This event is commonly
called a “squib load” or “pop and no kick” and is char ac ter ized by a reduced report
and little or no move ment of the slide. An alert operator could notice the oc cur rence
of this event in time to avoid firing the next cartridge.
Selection and Use of a Holster
Selection. When selecting a carrying holster for the USP Pistols, it is important to
consider the following points:
1. The holster must not make contact with or ac tu ate any of the operating con trols.
This includes the ham mer, slide release, magazine release lever, and most im por tant-
ly the trigger. The de sign of the holster must also not actuate these con trols when
the pistol is carried in, drawn from, or returned to the holster.
2. The holster should not cause the slide to move (un lock) when the pistol is returned
to the holster.
3. Accommodations must be provided in the hol ster for any accessories that might be
present on the pistol.
4. Choose a holster designed specifically for the specific USP pistol.
returning the pistol to the holster. The USP Pistols space must be made “Safe” (or
cleared) prior to re turn ing it to the holster. The pistol is considered safe to return it to the
holster when:
1. All fingers are off of the trig ger and out of the trig ger guard and;
2. The pistol is “clear” or;
3. The hammer is in the decocked (down) position. (Different for LEM)
A list of manufacturers that make holsters for USP pistols is available at the HK website
or by contacting HK Customer Service.
WArNiNG: The pistol must never be returned to the holster unless the above
procedures have been fol lowed or injury or death could occur.
Storage and Transport
1. Store or transport the pis tol and its com po nents clean and lubricated.
2. Store and transport the pistol without cartridges in the chamber, magazine, or in the
storage con tain er.
3. Store and transport the pistol with the slide forward and the hammer down
(uncocked).
4. Clean and lubricate the pistol and its com po nents at least every twelve (12) months
during storage.
5. Store the pistol and its components in a clean, dry, dust-free en vi ron ment with
regulated tem per a ture con trols.
6. Store the pistol and am mu ni tion separately under lock and key.
CAUTiON: in the USP Pistol fitted with LeM parts, clear the pistol and release
pressure on the cocking piece and hammer spring by dry firing the pistol one time.
Only then can the HK Lock-Out Device be placed in the locked position on pistols
fitted with the Lock-Out Device.
