So it sounds like the hammer is not getting cocked back all the way when the slide blows back.

Could it be that there is too much wear on the underside of the blow back housing or the hammer?

The hammer and the bottom of the blow back housing are two parts that interact with each other. I have had used guns where the blowback housing was worn down enough that the hammer would not get pushed back far enough to engage the sear. Im not talking about a lot, just half a MM will do it sometimes.

I have also had guns where the hammer was worn down enough such that the slide would not cock it back all the way. I had to use a metal shim to add material to the hammer face.

What you can do is slowly rack the slide, while doing so watch the movement of the hammer. Observe how far back the hammer travels and the maximum it travels when racking the slide.

As it travels, you will notice it go down progressively, and reach a point where it starts to then move back upwards.

Try to stop at the point where the hammer is pushed back the farthest. IE cannot move any farther.
Then with the slide still in the same position, use your thumb to pull the hammer back until it engages the single action sear. This may help you see how much material may be missing for the slide to not cock the hammer. Usually its very little, like 1MM.

Regarding the racking issue, it will only shoot correctly after you rack it because by manually racking the slide, you are resetting the valve knocker. Seems like the gun may not be blowing back enough to reset the knocker.

Hope this helps. This is all based on my fuzzy knowledge building a KJW P229 that was shipped in individual parts.
