the slide does not run on the polymer rails, so if there is wear there, then it is the slide evening things out. Your OK, leave it alone, or get some fine 600+ grit paper and sand the ruff spots off the polymer rails. I use grease in my slid,e as it doesn't run like oil and will stay where u put it look upscott240 said:I have only had my Kahr for a few weeks now and only about 100 rounds through her and it just seems as if my slide is scraping up the plastic rails. Actually making grooves in the plastic and tearing up the rail making pieces of plastic hang off the rails. Is that normal and just part of the breaking in process. I put quiet a bit of break free clp oil on the rails and I just took it apart to check it out after sitting for a week and it looks like I didnt even put oil on it, should I be using some sort of grease or is there a better oil? I tried to take a pic but I cant get it to turn out
Mil-comm.com and buy that TW25 syringe grease, It is the best IMO and u can run a small line of grease right inside the slide rails with that syringe..
