Ruger 22/45 Mark III doesn't work after disassembled and reassembled. Please help!

[efeng9622]

I just bought a Ruger 22/45 MarkIII one month ago. I disassembled it and Reassembled yesterday, but now this gun doesn’t work any more as follows,

1)It can’t be dry fire even I can pull out the trigger.
2)When I tried to pull bolt ,it is not smooth like before.
3)I try to re-disassembly it and hope I can figure out the problem, but I couldn’t pull the mainspring housing out no matter how hard I pull the mainspring housing,
I guess there is one procedure I did wrong ,
When I do reassembly procedure, I need to “ squeeze the trigger and hold it, move the hammer fully forwards with a tool” but I forgot to do it and just pushed the mainspring body back. So , I guess now somewhere (maybe hammer ) is locked inside.
I don’t know what can I do now? Should I need to try to disassembly the whole gun or only Ruger or gunsmith can do that work? I hope someone here can give to me advice



Thanks!

You put it back together wrong. Go back and re-read the instructions, and check these out while you are at it....

igpoobah is likely correct. Your hammer strut missed the mainspring. Pull it apart and start again, you have to tilt the gun backwards upside down. sometimes a dab of grease will help it fit together better.

Tonight I finally pulled the mainspring housing out ( hit the gun) . But when I reassembled this gun, the trigger still didn’t work.
I suddenly found I lost that fire pin stop , I don’t know when I lost it and also don’t know if this can cause that the trigger doesn’t work? ( should not) But I will try to order that pin tomorrow from Ruger.
Now I have two questions,
1) About hammer position because I was confused by Ruger’s instruction book.
When I do reassembly, what is “ hammer should fall to its full forward position “ ? Is it the horizontal ( cocked) position or it is the vertical ( uncocked) position ?
2) You said " Your hammer strut missed the mainspring." If you mean I should let Hammer strut ride on mainspring ?
Thanks!

Those silly MKII's .......................happens to everybody their first time . Reread , redo , take to smith and ask him to show ya how !!

The hammer has to be in the full forward "fired" position. Pull the trigger and point the gun to the floor.
There is a sort of dimple in the housing where the main spring is, the hammer strut has to fall into that dimple, get some light up in there and hold the gun so you can see the strut swinging back and forth and kind of eyeball where it should be in relation to the housing.

Hi! Chawbaccer and everybody,
I eventually finished to reassembly it yesterday . You are definitely right.

I did 1). I used a pencil to push it to that position ( almost vertical , but not 100%)

About 2) I did it this time but I never know it before.

Ruger's instructions mention about 1) and 2) but I didn't do, but some web's instructions don’t mention 2)
Now I can fire it but I don’t do it now, because this gun has no fire pin stop. I need to wait until I get it from Ruger. I ordered it yesterday.
By the way, would you please tell me how I can directly use "Quote reply" ?
I find I can't do that and have to copy some other people's message and paste it before I write my message.

Thanks all of you.

There is nothing magic about the firing pin stop pin. You can use the shank of a drill bit of a size that fits snugly in the hole. In fact, the drill bit shank will probably be more durable than Ruger's pin.

Are you sure you lost the firing pin crosspin? The newer Mark III's now use a roll pin instead of a solid pin like the Mark II's and first Mark III's. If you are missing the crosspin, the firing pin will just fall out of the bolt if you turn it upside down. If it doesn't fall, take a real good look to see if there is a roll pin in there.

Kruzr,
Thank you for letting me know and someone already sent a picture to me
to mention about this.I think my pin is a " hollow roll pin " or " roll pin" but I am sure I lost it. I will see it tonight and let you know.

Thanks!

I checked, my bolt should to be installed a "roll pin" , I have to wait until I get it from Ruger.

Thanks!

If the pin is missing, you better make sure you have the rebound spring and plunger under the firing pin. You should be able to simply lift up the firing pin and look under it if the crosspin is missing.

Kurzr, Thanks!

Tonight I re-checked my bolt carefully and believe that actually the roll pin is installed. the roll pin is hollow . I think why a lot of people believe the pin lost because the pin is hollow and small, you can use something insert the hole and cross the hole, then you will believe there is nothing inside and the pin is lost.
But now I have a further question , how can I disassembly this pin and fire pin in case I need to do ( for example if my fire pin is broken and I need to replace)? Will I get any trouble if I disassembly this area?

Thanks!

 

[Kruzr]

The bolt disassembly is the same as it was before except now, you have to use a punch to drift the roll pin out and then replace it. It will come out from either side. If you use a roll pin punch, you may be able to reuse the pin. If not, the end is usually flattened and the pin needs replacement if taken out.

Kruzr,
Thanks for letting me know. I will not do it until I have to do. but I will keep
in mind.
Thanks again for you helping me a lot.
