For disassembly place the gun in one hand with the top rear of the grip in the web of your thumb and your fingers wrapped around the top of the slide. Your fingers provide the pull to get the two marks on slide and frame lined up. If you do this with your left hand you can then turn it and the gun over and tap the end of the slide stop/takedown lever with a non-marring object to get it past the spring detent. Once you've broken the gun down several times it become easier to pop that out and you can just use a thumbnail to pop it out of the frame. If you put the gun in your right hand you can use a fine-bladed small screwdriver to insert under the slide stop to pry it out past the detent. Carefully so as to not mar the gun. That way you don't have to turn the gun over and lose sight of the alignment marks.
Any of us who've owned Kahrs for awhile have performed "gunsmithing" chores to one degree or another over the years. What did you have in mind?
