Field Stripping and Cleaning
Your firearm is a mechanical device and it needs to be cleaned and lubricated periodically. The HK VP40 Tactical should always be field-stripped prior to cleaning. Never clean a handgun from the muzzle end.
The VP40 Tactical’s disassembly is safer than that of many striker-fired guns. The trigger does not need to be pulled in order to field strip the gun. The takedown lever will not rotate to the unlocked position if there is a magazine in the gun or if the slide is not locked back. Rotating the takedown lever also de-cocks the firing pin if it is in the cocked position. Proceed with disassembly by following the directions provided in Section 6 (this section was not labeled properly) of the operator’s manual provided with the pistol. Cleaning and lubrication is described in Section 7.
Don’t forget to perform the “Function Check” described on page 24 of the Operator’s Manual after re-assembling the VP40 Tactical. If your VP40 Tactical is going to be used for self-defense, I always recommend firing at least five rounds through it after cleaning just to make sure that the pistol functions properly.
