View Full Version : What size are the grip screws on a Kahr MK9?

I found a grip screw missing and went to the Kahr site to secure a replacement. $1 per screw plus $6 shipping seemed a bit high, and there was nothing else I was interested in on the site at this time. So, anyone have any idea what the screw size and thread rate is? I was hoping it wasn't proprietary to Kahr.

I DO NOT know for sure about the MK9, but my older stainless K9 uses standard 1911 grip screws that have shortened threaded portions.

I've altered 1911 screws to fit K9 and K40 guns by grinding the shanks shorter.

When shortening the screws, BE SURE to get them the same length as the Kahr screws, otherwise they will protrude into the magazine well and will scar the magazine, or cause it to jam in place.

After shortening, use a fine file to clean up the burrs left on the end to prevent cross-threading.
