I fired about 800 rnds from it with a span of a month, using mostly Winchester 230gr FMJ and Sellier and Belloit 230 FMJ. I cleaned after every session (4 sessions in all) with the recommended MIL-L-63460 (CLP) and followed the procedure strictly from the manual. One problem found was on the exterior slide. The black color before, now has grayish and brownish color stains and spots all over. The other stain found was on the right side of the barrel, below the HK LOGO and serial number. Theres a brownish stain underlining the serial number. I dont use hoster. I just carry and store it in the factory hard case.
Does anybody here has the same problem??? Is there anyway we could removed this???? does the black finish thinning thus becoming gray??? then brownish???
Already informed HKUSA bout this and still waiting for reply. I did not expect for an expensive gun with HK brand to have a finish like this.
