A very simple DIY upgrade that requires some basic drilling skills. In Tanaka/KJW rifles, the trigger spring pushes against a plate sitting between the actual trigger and the spring itself. This plate has some circular cavities that should help the spring to stay in place. By further drilling into the cavity that the trigger spring sits into, it is possible to make the spring to keep its intended pressure point, better. It could happen that, when moved around, dropped or under general heavy stress, the trigger spring would bend all the way up and therefore apply a wrong force vector onto the trigger plate.

In the pictures you can see the stock trigger plate and the drilled one. In the last two pictures you can see how the trigger spring now sits all the way into the trigger plate cavity.

hello sir: just want to ask; did you drill the hole all the way in?

No, I just increased it by going half way through the trigger plate. If you accidentally puncture a hole through the plate I think the trigger will work anyway..but half way through or a little more than that is going to be enough since the trigger and the spring can't really move that much around..

nice;will do this to my trigger assembly sir;thanks sir

You're most welcome.
