Ruger 22/45 lockup...

Was shooting the .22 today and it stopped firing. The bullet itself is still in the brass (or partially so) as seen from the muzzle and the hammer did fall on that round.

The slide is stuck fast in the closed position and will not move at all despite a pretty fair amount of force in an attempt to do so. Tap, rack ain't gonna do it.

Looks like a trip to the gunshop here, but what might the diagnosis be? Thoughts?

I don't know enough to speculate on the cause or cure here but my suggestion is to go to:

and ask Bullseye to help you out. He is a great smif on the Ruger .22 autoloader platform.

I'd use a small screwdriver and push the extractor plunger & spring back into the bolt until I could unhook the extractor from the case rim.

Then you should be able to pull the bolt back and lock it open.

Next push the round out with a cleaning rod.

Unless something really critical broke inside the gun, that should get the round out so you can take it apart and investigate further.

Based on your description the causes are two-fold; likely a heavily fouled chamber and a dud round. The problem is - you have a round stuck in the chamber and cannot extract it by retracting the bolt. The danger is - even though your hammer fell, and the firing pin struck the case rim, you still have a live round in that pistol! Sometimes a rimfire cartridge won't fire from a firing pin hit, but due to inconsistent priming a rimfire dud round can often be extracted, rotated, and struck again, causing a detonation of the previously dud cartridge. Be careful attempting to extract that unfired round.

Unfortunately the procedure that rcmodel (while well intended) described above will not work. The mechanical workings of the extractor plunger and the firing pin stop will not allow the plunger to be moved far enough rearward by external manipulation to release the extractor. The extractor plunger will barely move rearward at all before it hits the stop pin. This small amount of movement is not enough to release the extractor's hold on your stuck case rim. There is a way to do this but it is somewhat involved, requiring the receiver to be separated from the fame. This shouldn't be a problem since the hammer is in the forward position. So, how involved do you want to get?

Is this 22/45 a Mark II or Mark III configuration?

It is a Mark III. I figured that round was live. I have the receiver off of the frame already, bullseye57. I would appreciate any help you could give.

If you already have the receiver off of the frame, then you can place it in a padded vise, to prevent marring of the finish. Lock it in the vise (barrel pointing upwards) and squirt some penetrating oil or a generous amount of Hoppes #9 down the barrel and let it soak a while. Place a non marring rod (hardwood dowel or a brass rod) into the bore from the open end and tap out the stuck round. Be sure to place a rag or padding under the bolt in case it releases and falls of of the case rim, again to prevent damage or marring. All you have to do is get the bolt to move out approx 1/8th of an inch, and you can get a jeweler's screwdriver in through the breech to release the extractor claw's hold on the stuck round's rim. Once you release the extractor's hold, then remove the bolt from the receiver. Then you can resume safely tapping out the stuck cartridge from the barrel end with the rod. Once the round is out give the chamber a good scrubbing with solvent and a bronze wire cleaning brush. Reassemble your pistol and you should be good to go.

Hope this helps.

Got it. I must be shooting some dirty ammo. I just picked this gun up as a trainer for my wife, but I have to get some cleaner shooting .22 ammo. Thanks, Bullseye.

Anytime! I'm happy that I could have been of some assistance to you.

Don't forget to use a bronze cleaning brush and scrub out that dirty chamber. I put the brush into the chamber through the rear of the receiver and then rotate it vigorously in the chamber to scrub. Don't push the brush too far or it will bind in the barrel's lands. You can add a solvent soaked patch to the cleaning brush and scrub with that. But don't do as I have seen others do many times, don't dip your bronze cleaning brush into the jar of solvent. You will contaminate the solvent and reduce the solvent's properties for removing brass and copper fouling. Soak a patch and then wrap it around your brush, that way the brush doesn't directly touch the fresh solvent.

What brand of Ammo were you shooting?

remington big box, 525 rounds per. I will just get in the habit of having a cleaning kit w/ me when I take it out. Spoiled by my glock.

If there is any worse .22 ammo, I haven't found it yet!

My MK3 target had all kinds of problems when I tried the Remington bulk stuff. Change ammo and don't look back. I put over 700 rounds through the MK3 on Sunday without a problem, mostly Federal 510 stuff from Walmart.

I was fairly certain you were going to say Remington, either bulk or thunderbolts. I avoid Remington 22LR like the plague. Ruger 22 Auto pistols especially do not function well with this brand. Remingtons tend to lead the barrels and chambers very heavily. Try some Federal bulk if you want budget ammo. It will run cleaner in your Ruger 22/45 pistol.

Hope this helps.

I too have a 22/45 and can attest to the fact that the 525 boxes of remington .22 cartridges are dirty shooting; the Thunderbolts really lead the barrel. The brass plated are not as bad. After reading this thread you can be sure I'll clean the pistol more often.

Add my Mark III Hunter to the Remington bulk hater club. I get a misfeed at least once every 20 rounds with that stuff.

Even the bolt action rifles won't eat Remington bulk. The only gun we have that likes it is DD's Hi Standard revolver.

Try the Federal bulk pack. My Ruger likes that stuff.
