Ruger mk iii 22/45 trouble

Post by foghern » Sat Jun 09, 2012 11:13 pm

Today I purchased the above pistol pre-owned from a gunshop. Got it home and the internals were filthy so I decided to break it down for a much needed cleaning(didn't strip it all the way).

After cleaning I started reassembly. Everything went smoothly... until I started putting the main spring housing back in. It was being very hard to push back in, probably the first time the gun was taken apart. I've read that it has to be forced in for the first few times so I forced it back in.

My problem is this. Now the bolt will slide back but gets stuck, and it will not cock or fire. Wouldn't be a problem except the main spring housing will not come back out, tried prying with a screwdriver, pliers, nothing will work. I can fix the not cocking and firing if I can get the damn thing back apart. Any advice would be much appreciated. Not really wanting to go to a gunsmith to have them take it apart if I don't have to.

You've probably pinned the hammer strut into/against the frame and not on top of the mainspring housing. There is seriously no good way to describe how to do it. You need to kind of hold it upside down, do a flip motion to send it back on top of the mainspring housing when you are reassembling. I.ve had mkii and mkiii for about 20 years, and i still suck at it

This will probably fix your proble: you need to get the hammer to drop. Get the bolt forward, insert an empty magazine, flip gun over and point the gun at about 60 degreees down and pull the trigger, remember EMPTY MAGaZINe!!!!!!! When the hammer drops you may not hear it, it isnt under spring tension, but you shold be able to remove the mainspring housing then. Since it isnt under tension, you'd think it wasnt cocked, but it is.


Hope the helps, mkiii has an magazine lock that you cant drop the hammer without a magazine, hammer back = no dissaembly

Dont shoot yourself, ymmv may vary, consult a congressman, etc. the advice above may be worth about what it cost you.

Odds are you may need to post this on a Ruger MK specific board. We may have a resident expert here, but those damn things come apart and go back together like some sort of stupid clockwork puzzle.

I just verfied the above on one of mine that i havent removed the magazine lock on, solved that exact malfunction. Youll probably have to hold the trigger down flip upside down, point down, and whack the muzzle with your hand a couple of times to get the hammer to drop. Worked for me fine

Ruger mk iii 22/45 trouble

I've been checking ruger mk forums and it seems like its just more time consuming and tedious to get it unstuck. Probably won't hurt to learn some kind of black magic to use on it too. Thanks for the quick replies, I purchased it as the store/range was closing so I'm really hoping I can get it back operational so I can shoot tomorrow. And I'm positive the mag is empty throughout all of this, I haven't even opened the box of ammo yet :D

Step 1) Hold the trigger down, flip the muzzle so it is pointing vertically straight up while holding the bolt assembly to prevent it from falling out;
Step 2) Take a small screwdriver, welding rod, chopstick or popsickle stick and jiggle the rear of the hammer side to side and back and forth until it moves into it's most forward position resting against the firing pin.
Step 3) Without changing the orientation of the muzzle (straight up), again attempt reassembly of the rear strap mainspring.

All Ruger Mk pistols have this same stumbling block, this has been a very common problem.

FYI - You should NOT have to force it, if you've aligned the hammer strut correctly with the spring in the backstrap you should feel tension but it should pop into place.

The trick is to get the hammer strut to hang down like a tonsil and align that tonsil with the backstrap mainspring.

I've done it dozens of times on my MkI and it still takes me a few minutes because of that hammer strut to backstrap connection.
Trying to force it into place will just make it worse.

Thanks guys for the advice, 2 mins after I started messing with the gun I was able to take the mainspring back out and put it back in right, looks like I will be going to the range today afterall! I'll probably post some pics in a new thread tonight.

When I ran our range, I would clean a lot of folks guns on the side - mostly the one box a year deer hunters. Ruger 22's brought a nice premium. I had more than a few brought out to the range in baskets/boxes, seems like those and mossberg shotguns are two of the worst offenders in the 'it came apart sooo easy' category.

My MK III 22/45 has been great- it's a tack-driver. But man.....assembly/dis-assembly really makes ya appreciate modern auto-loading handgun design, don't it?

Man oh man I had so much trouble with mine! I had to take it back to where I got it to have the gunsmith reassemble it!

Uh, is it really necessary to drop the hammer while it is still under tension from the hammer spring in the backstap to disassemble the MKII&III?
AFAIK it is not necessary to pull the trigger before disassembling the backstrap on the MKI at least.

Also, dry-firing rimfire =/= a good maintenance habit.

He dryfires @ 0:25 seconds

EDIT: Everything else seems like it's in the right order though. good instructional overall.

I have a MKIII 22/45 that I got late last year (the one with the threaded barrel) and I still have to tap the mainspring housing in and out with a mallet and a brass drift. It's MUCH more difficult than my old stainless MKIII ever was. I think the parkerization on the gun really closes up the clearances and makes it a tighter fit.

That said, the above posters have the right idea. You pinned the little hammer strut under the frame pin, in between the frame pin and the magazine well, instead of getting it hanging over the pin. where it can engage the mainspring.

It sucks. Hard.

Ruger mk iii 22/45 trouble

Post by Zack in CA » Mon Jun 11, 2012 5:11 pm

I tore my Mark III apart yesterday and it was about an hour and a half ordeal. I watched YouTube videos and checked pictures out on the web and finally got it all put back together. Ruger should put a warning label on the box about what a PITA it is to field strip and clean the mark series of pistol. Took it to the range today and ran 300 rounds through it and took back all those nasty names I called it yesterday.
I'm not saying its the start of the zombie apocalypse, but when a naked dude chews off the face of another dude and doesn't react to being shot, we should consider it.

Just for a quick cleaning this kit seems to make things MUCH better.

And to top it off they sell a bushing to take up the space of the mag disconnect on the MK-III. And also improves the trigger pull.

I give you the Ruger Hokey-Pokey:

You put the magazine in!
you take the magazine out!
You turn it upside-down and then you shake it all about.
You say some motherfuckers then you throw the pistol down
THATS WHAT ITS ALL ABOUT!
