Putting a shim in the joint works, but gets a bit fiddly as you fold and unfold. So here is what I have done. Open the stock (fold), unscrew the lock pin from the knuckle base. I needed vice grips as it has thread locker on it. File the base of the pin on the thread side. I used a hook file. If you file off too much, just set it to the depth that is what you want with a bit of blue thread
