Fix my gun Derya TM22 screw

I got the new Derya TM22 pro and after the first cleaning the middle top screw is very loose and doesn’t go all the way in.

It was pretty firm first time I opened it and now it is very loose. Should I change the screw or anything else?

I've avoided cleaning my TM22 because I heard the screw threads are very soft at the top.

If the threads are indeed stripped, you can consider get heli-coils (helical screw inserts) to reinforce the holes.

You can also try some threadlocker too.
