    Default How to detail strip a VP9

    This multi-part guide will show you how to detail strip an H&K VP9.

    Part 1 - Frame Disassembly

    Tools your will need
    • 1.8mm punch (or 1/16")
    • 2.4mm punch (or 3/32")
    • 2.8mm punch (or 7/64")
    • Trigger Rebound Spring (TRS) Tool (sold on HKParts)
    • A bench block (optional)
    • Small hammer or mallet




    Step 1
    • Make sure gun is unloaded. Check and check again!
    • Remove the slide
    • Leave the Disassembly Lever in the downward position




    Step 2
    • Rotate the Disassembly Lever towards the front of the muzzle about 10-15 degrees
    • Lift and pull the lever out of the frame






    Step 3
    • Make note of the position of the Trigger Round Spring (TRS) legs. The right leg is resting on the frame while the left leg is resting against the trigger.





    Step 4
    • Locate the Safety Clamp on the right side of the frame
    • Using a punch, push it up and out of the frame






    Step 5
    • Wiggle the Right-Side Slide Release Lever (up-and-down motion) and pull it out of the frame. Cover the TRS area with your hand before removing the Slide Release Lever because as soon as you pull out the lever, the TRS will come flying out. You do not want to misplace this spring!




    Step 6
    • Remove the TRS




    Step 7
    • Locate the Disconnector. It sits between the frame (right side) and the Trigger Bar
    • Lift it up and remove it from the frame

    • Using the 2.8mm (7/64") punch, drive out both the Roll-Pin and the Clamping Sleeve. It might be easier to punch out the Roll-Pin first, followed by the Clamping Sleeve.




    Step 9
    • Look inside the Locking Block and locate the Trigger Stop Bolt
    • Using a small punch, push out the bolt (to the left side of the frame)
    • Remove the bolt from the frame







    Step 10
    • Lift up the Locking Block and remove it from the frame




    Step 11
    • Locate the Left-Side Slide Release Lever and its spring. Remove both from the frame




    Step 12
    • Remove the Dismounting Safety and its spring from the Locking Block





    Step 13
    • Find the Catch Spring for Disassembly Lever on the right side of the frame
    • Lift it up and remove it from the frame

    2. Left-Side Slide Release Lever
    3. Dismounting Safety
    4. Elbow Spring for Dismounting Safety
    5. Left-Side Slide Release Lever Spring
    6. Locking Block




    Step 14
    • Make note of where the Trigger Bar Spring mounts on the frame



    • Lift up the Trigger Bar and remove it from the frame





    Step 15

    • Using the 2.4mm (3/32") punch, drive out the roll-pin





    Step 18
    • Wiggle the Magazine Release Lever out of the frame. Watch out for the flying spring

    Parts identification:
    1. Magazine Release Lever
    2. Roll-pin
    3. Spring




    Step 19
    • Locate the Backstrap roll-pin
    • Using the 2.4mm (3/32") punch, drive out the roll-pin
    • Remove the Backstrap

    Part 2 - Frame Reassembly

    Step 1
    • Insert the Magazine Release Lever Spring into the Magazine Release Lever
    • Carefully insert the lever into the frame. It needs a little wiggle to get it sit properly. Use a small butter knife/blade to compress the spring when sliding it in





    Step 2
    • Using the 2.4mm (3/32") punch, while applying a little downward pressure on the lever, tap in the roll-pin until it sits slightly below the surface




    Step 3
    • Insert the complete Trigger Housing into the frame, making sure the rear of the housing is pushed up against the back of the frame
    • Check to make sure the tang on the housing is visible in the little cut-out on the frame (circled in Red)
    • If the housing is not positioned correctly, the roll-pin hole on the housing will not line up properly with the hole on the frame





    Step 4
    • Make sure the roll-pin hole on the Trigger Housing is lined up correctly with the roll-pin hole on the frame (circled in Red)
    • Make sure you're using the correct Clamping Sleeve. There are 2 long Clamping Sleeves, one for the Locking Block and one for the Trigger Housing. The one for the Trigger Housing is the shorter one and the one for the Locking Block has a Roll-Pin tucked inside
    • Temporarily insert the Trigger Housing Clamping Sleeve into the frame and, using the 2/8mm (7/64") punch, drive it in




    Step 5
    • Insert the Catch Spring for Disassembly Lever into the slot on the right side of the frame. Note the orientation of the spring
    • Make sure it is positioned correctly on the frame





    Step 6
    • Lay the Locking Block on its side, as shown in the picture
    • Locate the indentation on the Locking Block where the Catch Spring for Dismounting Safety will be mounted




    Step 7
    • Mount the spring inside the indentation on the Locking Block as shown. The longer leg of the spring points downward
    • Note the small hook on the Dismounting Safety (circled in Red). When the Dismounting Safety is flipped over and mounted on the Locking Block, the longer leg of the Catch Spring will rest on the upper side of this hook




    Step 8
    • Flip the Dismounting Safety over and carefully mount it on the Locking Block, laying on top of the Catch Spring
    • Note how the spring is compressed and where the leg of the spring is positioned above the hook on the Dismounting Safety
    • To check if the Dismounting Safety is mounted correctly, push up on the safety and you should feel a little tension





    Step 9
    • Drop in the Trigger Bar (with complete Trigger) and carefully slide it into place




    • Tuck the other end of the Trigger Bar Spring into the cavity on the frame
    • Note how the Trigger Bar Spring is mounted on the frame




    Step 10
    • Mount the left-side Slide Release Lever onto the frame
    • Note the notch on the lever for the Pressure Spring






    Step 11
    • Locate the notch on the left-side Slide Release Lever where the Pressure Spring will be positioned (circled in Red)
    • Drop in the spring





    Step 12
    • Drop in the Locking Block, making sure the Dismounting Safety does not fall off while inserting the Locking Block into the frame
    • Make sure the Trigger is positioned inside the Locking Block




    Step 13
    • Insert the Disconnector into the frame. It will go to the right of the Trigger Bar, against the right side of the frame
    • Note the location of the Disconnector and Trigger Bar in relation to the Dismounting Safety






    Step 14
    • Line up the Disconnector, Trigger Bar, Locking Block and insert the right-side Slide Release Lever
    • Insert the lever just enough so it protrudes slightly past the inside wall of the Locking Block (to leave room for the insertion of the TRS in the next step)





    Step 15
    • There are 2 eyelets on the trigger itself. In the picture below, note the bare-metal color eyelet (the one located on the left-side of the trigger) and the other in black color.



    • Grab the Trigger Rebound Spring (TRS) using the HKParts TRS Tool as shown and insert it into the Locking Block with a little downward pressure





    • Pay attention to the position of the legs of the TRS. The left leg rests upon the frame while the right leg rests against the top of the trigger, right up against the right side of that bare-metal color eyelet





    • A close-up picture showing the position of the right leg of the TRS. For orientation purposes, the left side of the picture is facing the muzzle end of the frame




    Step 16
    • Push the right-side Slide Release Lever all the way in and through the TRS. It should lay flat against the right side of the frame
    • Insert the Trigger Stop Bolt into the frame as shown
    • Push it in until it sits slightly below the frame






    Step 17
    • Locate the roll-pin hole for the Locking Block on the frame (circled in Red)
    • Using the 2.8mm (7/64") punch, drive in the Clamping Sleeve (with Roll-Pin)





    Step 18
    • Insert the Safety Clamp into the frame
    • When fully seated, the clamp should sit flush with the top of the Locking Block






    Step 19
    • Insert the Disassembly Lever into the frame





    Your frame is now completely reassembled!
