If you call Kahr, someone will be able to tell you what the frame is made of. If your gun came with a box, you may be lucky enough that the original Kahr product code is listed on a sticker on the case. If you look in one of the manuals, they list codes that indicate what the gun is made of. One code not listed is “BOX”. That stands for Black Oxide-coated Stainless Steel.

The reason I mentioned the BOX finish is that my MK9 was made in 2003, and has a BOX slide on a stainless steel (matte gray) frame. That slide looks very different than my black DLC finish on my 2012 P380. The DLC finish on the P380 is “blacker” than the BOX coating on my MK9.
