    I'm getting frustrated. I've been trying thirty minutes to get it right, but nothing's worked. If anyone's familiar with the MK1, you guys may understand me when I say that I Cannot get the back-strap mechanism that locks the bolt into the frame of the gun via the two open holes to stay. I'll get the small cylinder through both holes and the bolt between them fine, but when I try to push the backstrab unit back into the back of the grip, the leverage of the entier piece makes the cylinder back out of the top hole and the spring mechanism to which it is supposed to catch. I have no idea what that backstrap piece is supposed to latch into.

    Can anyone help me out?

    I think there's a faq somewhere on THR, but if you can't find it, check this site.

    That's for a MKII, I don't think the MKI's frame comes off like that...

    I don't own a MkI but I was pretty sure that they are the same as a MKII with the exception of the bolt hold-open (MkI doesn't have one).

    That link has good instructions, and those things are not easy the first (or second) time. It gets better easier, though, and they are great 22s.

    I have a mark 1 also and took the darn thing apart. Big mistake. I think if finally turned the pistol upside down to get that dang so called backstrap mechanism to go into place. It was a real hard assembly.

    Good luck. I wish I could remember exactly how, but that was 30 or 40 years ago. Don't get mad and take a hammer to her, just keep trying. Eventually it will slip right in.

    Oh no, I'd never get mad and hurt it. It was my grandfathers gun. But I've got a problem...

    I got the backstrap back in by depressing the trigger while slipping it in. Went in very, very easily. I figured "I did it!", but then I tried to work the slide and it would go back about half an inch before stopping completely. No budge. I took the backstrap off to try and see what the problem was, but the bolt wont come out at all, it still stops at that same point. I'm taking it to a smith tomorrow while I'll be visiting my sister (she lives in the town with my favorite gunshop/smith). I need to have this thing fixed, but I'm afraid I don't know what else to do.

    God you people are no help! :D

    It's headed to a smith tomorrow. I'm sure she'll be able to fix it up nicely.

    Do you mean to say when you swing the mainspring assembly back into the frame, the bolt-stop pin pulls free and you're basically back at step 1?

    If that's the case, the bolt stop pin is NOT all the way in. You may need to tap the back of the mainspring assembly with something to get the bolt stop pin to move the extra half inch or so it needs to in order to be properly seated in the frame. Once the bolt stop pin is FULLY seated, the mainspring assembly will swing in and out of the frame effortlessly. Except for the last 1/8" or so, where you'll need to PUSH it gently. If it just plops in and sits flat against the frame, you don't have the hammer strut where it needs to be.

    Most likely what you need to do is:

    Pull the mainspring assembly out.
    Look in the slot in the frame and you'll see the hammer up at the top.
    If you can't see the slot in the back of the hammer, it's NOT all the way forward. Look at this pic... See the slot? Mucho important.
    Push it ALL the way forward (this is the key!), keeping the gun tilted "butt up" a little to keep it there if you need to.
    Reinsert the Mainspring assembly and push the bolt stop pin as far as it will go easily; tap it home the rest of the way.
    (You'll feel it when the bolt stop pin is properly seated (expect about a 1/2 or so beyond what you can do by hand)).
    Holding the pistol level now, swing the Mainspring assembly into the frame, and look for that last 1/8" of resistance.
    If it's there, swing the lever home into the mainspring housing and see that the bolt moves freely.

    Just one question: are you woking out of an intsruction manual? I seem to remember this exact thing happening with my MKII, so I just stripped it back down and started at step one of reassembly. I dissasemble my MKII almost every time I clean it, and after the first few times all the parts were broke-in and everything came apart and went together slick. I do reccomend the use of a hardwood dowel when pushing the backstrap rod through the reciever and bolt.

    I just got past this very problem about 15 seconds ago.

    A Saint by the name of python357 at the Glocktalk forum had suggested that one needs to Point the Gun Skyward, pull the trigger, and slide the Mainspring Housing back into place. It worked perfectly for mine. :)

    Since it wasn't found here (but this page was found first by Googling), i figured I'd shorten everybody's searches.

    Deer Hunter, Sorry I did not see this call for help last night. Hopefully I caught you before you went to the gunsmith. The Mark I fieldstrips the same as a Mark II pistol.

    Your hammer strut has slipped off of the mainspring cap and is stuck behind the frame crosspin. The bolt retracting 1/2" and stopping is the give-away clue for this problem. Here's a trouble shooting chart for Ruger 22 Autos http://www.guntalk-online.com/TroubleshootingPage.htm Your problem is #8. Easy to fix, just follow the prescription column. If that doesn't work then the second prescription on problem #1 will get that hammer forward for you. Open up the mainspring housing and you will see this -

    Use a paperclip and pull the hammer strut out from behind the pin. Reassemble using these instructions http://www.guntalk-online.com/fsprocedures.htm#reassemble and pay particular attention to step #8.

    Hope this helps.

    R,
    Bullseye

    Thanks for the help

    Anticipating the misery of trying to reassemble my Mark I as memories from 10 or more years ago still remain, I put the gun back together in about 30 seconds. Thanks to this forum, I understand what need be where when taking apart. putting together.

    Glad I did it as there was buildup of powder, oil and whatever all over.

    Thank you. Thank you. Thank you!
