I had so hard time trying to put 22/45 back together..
The main problem is

1. Hammer blocking mainspring housing.. If I force the mainspring housing arm into the slot, the bolt stop pin will leave leave the bolt

2. Hammer blocking bolt from fully retracting.. Once I managed to put everything back together, the bolt can only be retracted for like an inch... Sometimes if I pull really hard on the bolt I does fully retract but not smooth at all, and something else works weird (mag drop button stuck in the middle, mag does not move, or it's nearly impossible to push down bolt hold open button)

The manual and video says to dry fire it at different angle with mag in to manipulate hammer position but it does not always work.. once it's decocked I can't cock it because the bolt can't be fully retracted...

It took me like 3 hours to put it back together... hope it works this time...

Any thoughts on the correct hammer position during reassembly? Was I doing something wrong? Thanks

I guess this is probably the hammer position that was causing problems.. Once the hammer gets into this position, the only way to make it horizontal is 1. insert the mag 2. push it forward 3. pull it all the way backwards... During normal operation, the hammer is never supposed to go this far forward, isn't it?

I'm not sure about how the mkiii operates, I took the mad safety out of mine. But on reassembly the hammer goes the the rear to install the bolt, then it goes full forward to install the mainspring.

How do you make it to go full forward? Once it gets full forward it blocks the bolt sometimes

Put the bolt in
look into the main spring housing gap in the grip
push the hammer forward
install main spring housing

After you do it a couple of times, you will wonder-- what was so hard

If you can reassemble the gun and the bolt only retracts partially, that means the hammer strut is caught behind the frame of the gun and not falling into position on the MSH.

Hi Random Gun,

I have the same problem with my MkIII 22/45. I think I'm following directions, reassemble it, and the bolt only goes back an inch or so. Arrrgghh!

What I do now is watch this video EVERY time I reassemble my pistol.

I know others say after a few times reassembly becomes easy. It never did for me. Pointing up, pointing down, pulling trigger, popping mag in, popping mag out, it never made sense to me and when I don't grasp the concept of the why I have a hard time remembering the how.

I'm a pretty smart fellow. In fact I'm so bright my Mother calls me Son! Couldn't resist. But seriously, google YouTube and hopefully you'll find a video that works for you.

Now my routine is shoot, disassemble, clean, watch video, reassemble, SMILE and look forward to the next shooting experience. That's a bit different than it used to be.

Good Luck!

Dan

Thanks guys.
#6 Squeeze trigger and push hammer fully forwards (uncocked position )
That's where I was having issues. I squeezed the trigger but the hammer didn't move... It felt like the trigger was disconnected..

Last time it took me like 3 hours to put it back together.... after 30 some retries everything magically fitted into one piece....

I used to cuss my Ruger Mk II every time I cleaned it. Then I bought a Majestic Arms Speed Strip Kit from DrFrankenRuger webstore (fits Mk II, III, 22/45). Once installed, all you have to do is use an allen wrench to remove the bolt stop pin from the top of the pistol, pull the bolt out the back!! And the kit comes with a replacement 3.5 lb hammer and take-up bushing you can install while putting in the kit. Best $$ I ever spent.

(P.S. I'm not associated with that seller in any way.... I just like the product that much.)

Or..... if you don't want to install the kit, then try the procedure shown in this video.
Just remember to follow EVERY step as shown.

IIRC, reassembly goes like this:

1. Put mag in, aim gripframe upwards, pull trigger, push hammer back. The aiming upwards is important, as it keeps the hammer push rod from binding
1a. Remove the mag. It's only there to disengage the mag safety.
2. Reinstall the receiver/barrel assembly. I always have to use a mallet (on the grip frame) to get mine aligned properly.
3. Reinsert the bolt.
4. Reinstall the bolt stop pin
5. Aim the pistol upward again, and close the mainspring housing/takedown lever. You'll feel the spring tension when it's most of the way in. If you don't, don't force it.
6. Reinstall the mag, and dry fire.

My gun is a Mark III, not a 22/45, so it may be slightly different, but it's not a huge difference.

You need to look at the Ruger factory videos. They have upgreaded them and you should not have a problem IF you follow the directions step by step.
They're under the "tech tips" menu tag.
