KWA KP.45 / KSC USP frame disasembly
« on: January 17, 2010, 05:17:54 PM »
So...there hasn't been a guide for years. This guide will work on both old system and new system USP/KP.45s

Disassembling a KWA/KSC USP frame.

Do this on a clean surface with no way to loose parts and lie out parts in order similar to how they came out for easy reassemble.
*please refer to this diagram for the names of parts. (#) is the part number. (Its a GREAT idea to print this out and have near you.) http://img138.imageshack.us/img138/3949/diagram.jpg


READY? Go!!!

Start with the frame in hand and remove the slide stop spring (82)



Next remove the hammer strut spring (77) and the stopper (90) by removing the pin (88).



Push the sear pin (61) flush with the metal.



Remove the decocking plate (78).



Now remove the sear pin (61).



The decocking bar (57) just slips out as soon as the sear pin (61) is out.



Next pull the decocking lever retainer (72) out



Pull the impact block extension (65) up and out of the way for now.



Rock the disconnector (71) and right sear (60) left and right til they come out.





Rotate the decocking&safety lever (83) while pulling until it stops moving out.
You’ll get it about so far then itll hit obstructions. Pull back on the left sear (59) and compress down the decocking plate bar (79) with s small poking stick.  Then you’ll be able to pull the lever out.




Flip it over and the decocking plate (79) falls out.



Remove this bugger, the transfer plunger and its short (important) spring (56 (58)



NOW. This part is kind tough. Remove the hammer sleeve (74) but there are obstruction. Mainly the left sear (59)
1.pull the left sear (59) back and lever out the hammer sleeve (74) It won't go far but lever it out as much as it will go, I picture of the levering and where to lever is below.


moving the hammer back and forth throughout the hammer sleeve removal process is essential to its removal.


2. Theres a bit that comes of the left sear (59) and mates into a gap in the hammer sleeve (74) take that out of the gap and put it onto the ledge of the hammer sleeve (74) out of the gap.


3. The hole should be clear of obstruction with no metal sticking through the gaps to get it stuck.


4. Push out the hammer sleeve (74).




Hard parts outta the way now.

Onwards to victory!

Push out the trigger pin (53).



Remove the inner frame screw (48).




Lift up on the front of the inner frame (47) very gently. The back end will stay down still. You will notice that the hammer spur (76) and trigger transfer bar (54) come out here.






Now push the trigger (50) in a bit and lift out the back of the inner frame (47).




Remove the decocking bar spring (80) that’s sitting in the outer frame (46)




Get back to the inner frame (47) and get the transfer bar plunger and the long (important) spring. (56)(55)




Punch out the trigger pin sleeve (52)


dis is what you get.





Now to remove the Strut pin (64(and it is shown)), you will need to make a tool. Get a small paper clip and cut a bit off of it and use it to punch out the strut pin (64) by inserting it into the smaller of the 2 holes and punching it out.








The impact block (66) and left sear (59) come out.






And you are done put it back together the opposite you took it apart it gets easier each time you do it.

there is the possibility that I only own 2 GBB pistols. In which case aiden would be right about me having done a disassembly guide for all of them.


Even tho everyone and their mom has done a guide on the WE hi capa I'll do one on it I guess...high resolution photos make a difference.

Hey, just wanted to say thanks again. :)
Kind of useless though to me, as my USP's trigger just cracked. This leaves me very sad face. :(

I've heard that you can replace it with a real steel trigger. Don't quote me on that tho you should research and find out.

lol will do the next time someone needs a pistol fixed.

TK, does the USP's subframe really look like that (kinda rusted) or does it need some TLC/polishing or both?

Yeah it looked like that outta the box
I bought it brand new from zerounit still had all the fresh oil on it and its frame really looked like that.

Its the color of the coating of the metal its plated with it.

Just to complete it, you should do a reassembly guide.  It looks different when you put things back together, and it would help a lot of people with fixes :).

Nicely done!

Thanks

I actually have all the pictures because I documented the reassembly but I don't feel the need for reassembly guide because its just the reveres of the disassembly and just putting the pieces in and putting a round peg through a bunch of round holes.
I know that deruty tested out my guide already and it went fine for him.

Just beleive in yourself and put it back together it will feel good knowing that you could.


If someone really needs one I'll make it I guess.
