Dang, I'm still looking for the TV remote so I can watch the 11:00 news to see how many people got shot today.....I think technology has left the building for this old man.....Nice looking grip extension MahrLalk, no idea how you made it but I'm impressed, don't worry about me uploading it, I'm still trying to download lunch......Oh one last thing, I think you seem to be the right guy with the skills to fabricate a product that will sell and make money for you, tool up a "butt plug" (not a bad word) to fill in the rear of the gap in a Kahr grip so it doesn't look like something is missing and you will sell a bunch of um.....There are several company's selling Glock plugs to fill in the void in the grip but nobody has done it for Kahrs so you may have found a new market for your 3D printer skills and abilities and I'd be a customer.....
