FWIW:
I had a P11 a few years ago and it was always reliable, and at self defense range was accurate enough.. Beyond 7' or so I couldn't hit the broad side of the barn, from the inside, with it.
Pulling the slide back was like pulling sandpaper against sandpaper and I had been spoiled by other more expensive pistols so never could get over the gritty slide action and poor accuracy beyond self defense range.
But having said that, I sold it for just what I paid for it, it never faultered once, and it was certainly worth the price...
For someone who doesn't want to put a lot of money in a compact 9mm pistol I think the KT P11 or PF9 are very good choices.
Just personal opinion, no offense to those who might disagree.
