Four Kahr pistols here. One had a spring issue, and once that was determined, it was an easy fix. The "do not overtighten" caution is just that, a caution. Worst case - you over tighten and strip out some polymer. Hello JB weld or Accraglass or other strong epoxy type filler. Actually... if you use some stainless powder in with Accraglass, its stronger than the original poly nylon-66 is. But try not to strip the screw out. Its easy to just snug it up and forget about it for next to forever.
My own tweakage was due to the spring being bent laterally, which held the slide stop out laterally just a mm or so, and... it would occasionally hang up, only while hand racking. I thought it was my finger hitting it while racking, tried this and that. It was the spring. No biggie, out came the spring, a little counter tweak with needle nose pliers, in goes the spring. Done. Hasn't hiccuped since.
There are little grooves in the washer that hold it, so that once its positioned, it tends to stay put.
That's about all I can think of. Its something misunderstood, feared, avoided... by folks, but.... its just a little spring, easily replaced, and easily repaired.
