Mark III Wont Cock or Disassemble

Hello, my problem is my Mkiii 22/45's mainspring housing will not come out more than a half an inch. It also will not cock and the bolt oftentimes gets caught and will not close all of the way. When I open up the bolt and look through the magazine chamber, I see a stiff spur a little over an inch below the bolt that comes from the rear and the right and ends far enough out that it seems to disrupt the inserting of the magazine slightly. I can insert the mag, but it is stiff. All of the bolts on both sides of the gun seem to look normal.

Here is the story behind what happened. I fired 60 rounds, left it on the shelf for a month. I went to clean it but it did as I described above. Somehow I managed to get the gun to cock and it disassembled. I cleaned it and reassembled it and it immediately went into the condition I described above.

I was not diligent in following the instructions for reassembly. I have tried inserting the magazine, pulling the trigger, and hitting the muzzle against my desk with the hope of moving the hammer. This hasn't worked. I am afraid it has something to do with that spur.

Here is a picture of the spur.


Thank you for any help in this regard.

Firstly, welcome from Australia mate.
Glad to have you on board, nice folk here and lots of good info.
It is sad that your first post here poses a problem.
I have two MKIII 22/45's (10110 & 10140).
I have always found that if you disassemble and clean prior to shooting the first time you can eliminate problems along the way.
And you have to follow the instructions to a T.

Did you point the gun up when pushing the Latch into the backstrap?

First off Welcome!

I have done this a few times... not as bad as it sounds!! Sounds like the "shaft" on the hammer is caught, I say point the muzzle in the upright position. and shack the pistol with the main spring assembly out a bit, I found after a bit it will come free. All you need is to get the hammer free.

Hope this helps!

PS Read your instructions !!!

Take a look at bullseye's page - he may soon chime in.

2245 Maintenance Page

What has been said already sounds like the problem. You have to have the gun pointing up to get the hammer strut in the right place.

Working on the problem

Thanks for the responses. They haven't worked so far but I will keep trying. Judging from the pics on Bullseye's site, the "spur" is supposed to be there. If the shaking and pounding doesn't work, I need to find a way to manually move the hammer (if that is the problem). Another thing that might help diagnosing my problem is the bolt that is noted in the picture below likes to move it's way to the left. I am not sure if that is normal. Disregard this point if that's normal.



The main bolt (the one I pull back to cock the gun) doesn't get stuck midway if I have the mainspring housing loose.

It's great that you guys respond so fast.

Bulldog's Video

bulldog1946, I will try your technique in a bit. I saw the two videos (yours plus the one you responded to). The problem described in the original video is almost exactly like mine. So far no luck but I'll keep pounding away (literally)

I had the same problem and did exactly what bulldog1946 did and yes it worked. My advice was from the Ruger customer service and they were a great help.

What you have to do is manually decock the hammer to disassemble. On my troubleshooting pages I talk about moving the hammer by striking the muzzle downwards onto a block of wood, this is essentially what Ruger is now saying with the phonebook. The key is you have to move the hammer fully forward, which is not happening and why your mainspring housing will not open up fully, the hammer strut is inside the housing and will not allow it to swing out of the frame. Now the key to this procedure is to place an empty magazine into the Mark III 22/45 and squeeze and hold the trigger rearwards all while striking the muzzle downward onto a block of wood. Keep the barrel tilted down toward the block of wood. Don't be shy, hit it hard onto the wooden block. The wood is there to protect the muzzle's crown. You are trying to move the hammer by the inertia of the hit. Then release the trigger, remove the magazine and open up the mainspring latch. You may have to try it a few times to get it right and swing out the mainspring housing. But with a 22/45 you must remove the magazine to open up the latch, otherwise the mag body gets in the way and the latch cannot open up fully.

That little spur you referred to is actually the magazine disconnector safety hook. It is supposed to be there and needs to touch the magazine body to release the sear when you pull the trigger. It is part of the Mark III pistol generation upgrade.

R,
Bullseye
