HK45 & HK45 Compact
Inspection
During and after cleaning visually inspect the pistol and its components for
any irregularities that may cause problems or stoppages during its operation.
Generally, you should keep a watchful eye out for the discrepancies listed
below.
Always clear the pistol (Page 19) before conducting your inspection!
• Damaged or missing parts to include the barrel O-ring
• Improper assembly or function
• Absence of free movement, where applicable
• Absence of spring tension, where applicable
• Unaccustomed looseness
• Parts exhibiting signs of cracks, burrs, dents, or obvious signs of
damage or stress
• Presence of stops or tactile clicks, where applicable
• General overall cleanliness
• Presence of sufficient lubrication
• Presence of corrosion or degradation of surface finish
• O-ring within sound suppressor coupler
• Missing sight dots on tritium inserts
• Missing or loose sight retaining screws
CAUTION: This pistol has been developed by capable and experienced
engineers. Its present design represents an optimization of a combination
of safety, speed of deployment, accuracy, dependability, and durability. Do
not attempt to make this pistol "better" by altering any of its components.
Altering any part of the pistol or magazine may cause injury or death and
will also void any HK warranty on the product.
Lubrication
Metal surfaces of the HK45 are treated with HK's special “Hostile Environment”
surface finish protecting the pistol from corrosion and wear. This surface
treatment does not completely reduce the friction between moving parts and
it is recommended that a lubricant be applied to the pistol to ensure proper
functioning. Any type of high-quality, medium weight lubricant (oil) specifically
designed for use on firearms will work well on the HK45 Pistol. Do not use
lubricants that boast of their ability to penetrate metal as these substances may
enter into and deaden primers.
Where, and How Much
No Lube - Surface is dry and not slippery to the touch
• Plastic components
Light Lube - A finger run across the surface yields little or no lube
(1 drop)
• Bore, chamber, and exterior of barrel; including O-ring and muzzle
threads if applicable
• All metal parts
• All internal parts in slide and frame
• Magazine spring
• Recoil/buffer spring assembly
• Sights
• Magazine housing
• Barrel O-Ring and threads (if applicable)
• Sound suppressor O-ring and threads (if applicable)
Medium Lube - A finger run across the surface yields some lube but lube
does not run down surface when it is held in a vertical position (2 - 3
drops)
• Barrel locking block
• Slide rails and grooves
• All operating controls
• Detent plate & detent slide (items 45 & 47, see diagram on
pages 53)
• Locking insert and guiding part in frame
• Extractor
Heavy Lube - Lubrication runs down the surface when it is held in a
vertical position (4 – 5 drops)
No heavy lube is required on the HK45.
Reapply lubricant periodically during firing as it burns off from the heat. Apply
lubricant using a clean shaving brush, cotton swabs, patches, or rag. A spray
bottle of lubricant also works well when using compressed air to circulate the
lubricant into all parts and to remove the excess from the pistol.
The ten inspection criteria as listed in the Inspection section should be checked
prior to contacting HK if your pistol fails to function properly. Other common
causes of problems that are often overlooked include:
• Fouled or improperly lubricated pistol
• Bad ammunition
• Damaged magazines
• Operator error
If your HK45 still fails to function, contact your unit armorer or HK Customer
Service at (706) 568-1906 for assistance.
NOTE: If after reviewing this manual you still have questions, please contact
your unit armorer or Heckler & Koch Customer Service Department.
