    I have a Mark III that is just a kick in the pants to shoot, but now it needs a proper cleaning. When I flip the lever on the rear of the grip, I can't get it to lever outward. Any ideas?
    Thanks.

    I have the 22/45 which I believe is the next model after yours. With mine I flip the lever out GENTLY with a small screwdriver. Then it pivots in the bolt assembly. You pull the assembly straight down. Do you have a book? With mine if you don't have it pointing the right way, up or down, when you reassemble it won't shoot. If you need the book, I could probably scan a few pages for you.

    Are you remembering to dry fire it before trying to field strip it? That relieves all the tension on the mainspring and moves the hammer & strut. Call Ruger and request the free manual. Once you have manual in hand it'll be easy IF you go exactly according to directions.

    Duh, I haven't done the dry firing part. It goes against my grain to dry fire a .22. I'll try it now.

    Ruger field stripping

    Step #1 Verify the pistol is unloaded. Open the bolt and inspect the chamber.
    Step #2 Insert an empty magazine into the pistol.
    Step #3 Squeeze the trigger, listen for the hammer to "click". Note - Hammer must be in the fully up or uncocked position to proceed with the disassembly. Also the pistol's internal locking screw must be turned fully flush with the key to remove Mainspring Housing. (Picture here)

    Step #4 Open the mainspring latch and then swing the mainspring housing out of the frame well. (22/45 must remove magazine before unlatching mainspring housing)
    Step #5 Pull mainspring housing downwards to remove the bolt stop pin from the recevier. Remove the entire mainspring assemby from the frame.

    Step #6 Pull bolt rearwards until it is clear of the receiver. Note - Hammer will now be in the down or cocked position.

    Step #7 Remove the magazine from the grip frame. Caution - The receiver will not come off of the frame if a magazine is installed. (22/45 skip to step #8)

    Step #8 Slide pistol's receiver forward until it separates from the grip frame. (tap receiver with a mallet if necessary.) Pistol is now field stripped for cleaning or other maintenance.

    And reverse process to re-assemble

    It's clean and now I'm reassembling it. The bolt stop won't seat completely. It won't go about the last quarter inch. What am I doing wrong?

    The strut isn't falling into place in the mainspring carrier. Take it apart again. When reassembling, the bolt goes in, move the hammer all the way forward, hold the gun upside down and reinsert the "lever thingy" thru the bolt into it's hole in the receiver, start to fold the thingy back in while tilting the gun backward (upside down so tilt the barrel up) so the strut tilts back, fold it in all the way and close the lever...

    (Since you said Mk III, you'll have to insert the mag to move the hammer forward after installing the bolt. I removed the loaded chamber indicator and the mag disconnect from mine to make it easier))

    Good YouTube Videos on Mark III

    When I first ordered my Mark III, I found 3 excellent videos on YouTube by a guy named patriot36. For YouTube videos, he really did an excellent job with lighting, camera work, and a rare articulate narration. These are 3 10-minute videos worth watching...

    ruger mk1,2,3 are designed to be dry fired. you cannot hurt them by doing it.

    a simple thing for taking them down and putting together is the hammer has to be in the uncocked or fired position the remove or insert the mainspring housing. it then has to be in the cocked or ready to fire position to remove or insert the bolt. to get the hammer in the fired or uncocked postion with the mainspring already out pull the trigger and gently flick your gun holding hand forward so the muzzle points down. to get the hammer in the ready to fire or cocked position do the same thing but flick the muzzle upwards

    ruger's instructions make a simple thing sound very complex and confusing.

    Try as I might, I cannot get the pin to completely seat in the receiver. I've watched a bunch of videos and played with this thing until I'm frustrated. Then I go back and try again. I'm sure I've got it right, but the pin will not seat.

    As we spoke about, a tap with a brass hammer will solve that problem. Once they've been apart a few times it will get easier. Also, make sure the receiver is seated fully on the frame (if you took it down that far)...

    I did. Okay, it's time to head into the garage and try some hammer persuasion. I'll let you know how it goes. What a PITA. :rolleyes:
