Ruger Mk1 assembly

[RancidSumo]

I am haveing a hell of a time putting my Mk1 back together. To start with, one I get it all back together, the hammer blocks the bolt from being pulled back. Second, after an hour of trying to put it back together, the spring came out so I put it back in and now the firing pin is sticking up a little bit and makes the spring stick up a little so I can put the bolt back in. Any input on how to fix it would be great, especially on the firing pin issue.

I now have an even bigger problem, the firing pin stop is falling out and will not stay in.

The first problem is easy here's a link for an assembly procedure, just omit the installation and removal of the magazine, everything else is the same. http://www.guntalk-online.com/fsprocedures.htm

To keep the firing pin stop in place you can peen one end of the pin a little with a hammer and that will keep it from falling out during installation. Make sure that your firing pin rebound spring is in place. Here's a link to help with bolt assembly disassembly (near the bottom of the page) http://www.guntalk-online.com/detailstrip.htm

I just got to the point where I am not going to mess with it anymore. I am just going to take it to someone who knows what they are doing so I don't break the damn thing.

I just can't leave it alone. Anyone have an idea on why the bolt won't go in?

Once you have the hammer in the down (cocked) position, then you have to rotate the bolt a little to get past the ejector. It should slide into the receiver all the way. Once you get the bolt in then you flip the pistol upside down, push the hammer all the way forward (uncocked) position and insert the mainspring housing. Once the housing is in then slowly close it, tilt the pistol slightly rearward to allow the hammer strut to ride on the housing until you close it. Then close the latch.


Hope this helps.

I fixed the firing pin problem and now the bolt will go in up to the last 1/2 inch. Any ideas on how to fix this?

 

[Bullseye57]

The only thing that could be catching on a correctly assembled pistol is the recoil spring assembly bolt stop flange. Otherwise there is nothing blocking the bolt from closing, as long as a magazine is not installed in the frame. Try removing the recoil spring assembly and reinstalling the bolt, if it goes in smoothly then the spring assembly is causing the hang-up. One of the wings on the bolt stop flange may be bent a little and causing the problem. Check for any bent parts and reinstall the recoil spring assembly on the bolt and then the entire bolt into the receiver.

Hope this helps.

I am 99.9% sure that it is the recoil spring. I removed it and the bolt goes in fine. I just don't know what to do about it. The corners stick out a hair on both sides and when I jammed it into the gun (yeah I know, a bad idea) then it got stuck in there and it took a while to get it out. Should I just take some pliers and bend the corners in a little bit?

 

[RancidSumo]

Well I bent them with a pair of needle nose pliers and now it fits great. Now to go to that website you gave and figure out how to put it together.

And After 2 1/2 Days Of Being Pissed Off, The Gun Is Back Together!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Congratulations! Sometimes the little things can really get you going. Sorry I was away from the forum when you asked the question, pliers was the correct way to go. I'm happy to hear you don't have to make that trip to the gunsmith with a bag of parts. My web help pages are there to assist with those who are in need.

Good luck with that pistol!
