Thankfully, my experience is different. Of the 7 Pentax k mount lenses I own, all are good. Have you tried them on a different body? I don't know why you have such bad luck with Pentax.

1) How do you suggest I try them on a different body?

2) I would say that it's all down to very poor quality control.

I would say your issue is perception.

the top image is your Nikon the bottom your Pentax ,

One of them is very poor even for a cheap lens and it ain’t the Pentax !

Lets look at the other side

This time the Nikon seems to have the edge marginally sharper though the DoF appears to be massively different as if one isn't f1.8 !

What does this tell us.......

1 the Nikon is decentered to the left

2 the Pentax is decentered to the right

or

3 the photographer was not holding the camera perpendicular to the subject in either shot.

Come on what do you reckon is most likely ... every lens you own is decentered? or your testing is flawed.

I would note the Nikon lens is clearly optically inferior to the Pentax both sharpness and aberration control is visibly lacking in your Nikon lens it appears to be a poor example of this lens.
