KJW KP-07 Problem!

Recommended Posts

Hey guys.

I have been playing airsoft for about 7 months now but Im still pretty new. 4 Months back I bought a KJW KP-07 and since first week the gun had many lubrication problems, every month I gotta oil it and clean it all or it will jam or burst 3 bb's in one shot, but that's not the problem right now since that can be fixed with proper maintenance(kind of).

Now Im struggling with a jam on the Hammer, everytime I press the trigger I have to pull the hammer again in order to get another shot ( kinda like a revolver ). I seriously don't know what to do and though about asking for help online before talking with the guy who sold me this replica.

I would appreciate any kind of help.

*** I will add a video link of what's happening, I hope it helps***

******the paint is due to the law in my country please ignore, I know its ridiculous********

You may have a worn sear, most likely caused by wear due to improper lubrication.


You could also have a small crack in your Blow Back Cylinder.


Your not using silicone oil are you?


You should be using a light weight grease.


What Gas are you suing and what is the ambient temp when you fire the pistol?
