I've been doing detailed cleanings on all my guns this weekend. Got to the Mark III that I have never taken apart. I looked it up on youtube and followed the directions as posted by ruger. After using my 'non marring punch' to remove the bolt stop pin. I proceeded to tilt the gun up and pull the trigger to remove the bolt. Bolt came about about 1/3rd and stopped. Hmm. Must have done something wrong. Put the gun back together. Checked for function (everything worked fine), watched the video again and tried again. Same problem. Put the gun back together and function tested fine. Searched for other Mark II/III video's and saw the procedure was the same. Tried again. Same problem. This time when I put the gun back together I now have the same problem assembled. I can not pull the bolt back more than 1/3rd of the way. :angry: I've tried with and without the mag. I've removed the grips to look for any obstruction. The safty will not move if that gives any clues. Any tips before I call Ruger?
