polski, The instructions in "this" thread alone should get you squared away on assembly/disassembly of the Ruger MKI, II or III! There have been literally dozens of threads here on this very subject. This would be my suggestion to you. Take the gun to a local "competent" gunsmith and have him show you the "complete" technique of disassembly/reassembly of your pistol. Any gunsmith worth his "salt" should be willing to do this for you. If you have to, keep trying until you find one that will. Once you "see" a hands on demonstration with any or all of your questions answered, you should be "good-to-go"!..........................Dick :idea:
