Have you checked out any utube videos? If there aren't any check out how to disassemble a 1894 or 94. I believe these guns are almost the same. I think the biggest difference between the 1889s and 1894s was they changed the firing pin. I know there are videos on how to disassemble the 1894s/94s cause that's what used to take mine apart. It's a fairly easy take down process. good luck. If you have any problems shoot me a PM and i can talk you through it. joe
