Ruger Security Six Problem

I got a Ruger security six for helping rebuild an engine, but the cylinder will not rotate when there are rounds in it, the casing hits the frame on the right side as it rotates up into the firing position.

i checked the ammo we bought and its to speck.

i dont know any thing about the history of the gun like if it has done this before or what not.

any help would be awesome. thanks

Hi,
Where is it binding? Sometimes do to lack of maintance there is a build up of carbon around were the cylinder rotates. This can cause binding.

Good luck,
Howard

Did you load it with .357 or .38SPL? Lots of times, if the previous owner fired all .38SPL through it there will be some residue in the chamber that could keep .357 from seating fully.

I cleaned the crap out of it when i got it and again after we found out it was not working right... im going to try some higher end ammo, but it shouldn't matter, why would ruger make a gun with such tight tolerances?

Just for clarity's sake, you cleaned under the ejection star, and the face (front) of the cylinder?

We presume the loaded chamber closes easily and completely, yes?

And that it works perfectly fine EMPTY, yes?

Try loading ONE round and make sure it ends up at the 6 o'clock position. Does it rotate now?

It's possible the firing pin bushing has come forward, catching the rim of the upcoming cartridge.

I doubt ruger made a gun with such tight tolerances. Any Security/Service/Speed-Six is at an absolute minimum 25 years old. A lot can happen to a gun in that amount of time.
Check all the things mentioned above. If you can't find the issue, I am willing to bet that Ruger will repair it free of charge.

With the cylinder swung out, spin it slowly and look down the center axis. Does it spin true, or does it wobble a bit about the center. If it wobbles, you have structural problems with the shaft of the crane pivot assembly.

Yes things can happen to older guns over time, but not generally with the Security-Six and it sounds to me as though it's one of the issues above. I'd even go so far as to take the gun apart and reassemble it.

Make sure the rounds seat in the chambers and that they drop in and out with just gravity. If the rounds aren't positively seating, then it's some sort of throating issue. If they all dropping freely into the chambers, empty the rounds and ensure that the star is seating properly. If both seem to be operating well, empty the rounds from the revolver and close the cylinder. Now measure the barrel/cylinder gap. If it's more than .012-inch, the problem most likely is one that came from the factory.

Is the gun stainless or blue?

I suspect one of two things.

As Jamie said, clean under the star extractor any carbon buildup or unburnt powder.

And then make sure the extractor rod is screwed in tight.

Those two would be what I'd look at.

Then make sure the ammo you are using fits in another trusted .38.

Check that the screw below the cylinder thumb latch is tight.

If the previous owner fired a lot of .38spl in this .357 you could have a build up of lead in the chambers. This would stop the longer .357 case from fully seating. It only takes a few thousands to cause case drag.

Cylinder is true, every thing top and bottom is cleaned and polished its, stainless, rounds seat all the way, screw is tight, but its the other right side that its hitting the frame any way...


im going to send Ruger a letter see what they have to say.

Thanks for every ones help BTW. this one is stumping the heck out of me...

From your photo, it looks like the cartridges are not seating all the way. I know you have said that they are seating, but your photo sure looks different from my Security Six when held loaded at that angle. As suggested before, check the cylinder throats for lead buildup and clean them thoroughly. I think it will fix your problem.

Indeed, it looks like the ejector itself is not flush. I see what looks like the ejector sticking up proud above the cylinders, and that should be down flush. I've had a few minor fitting problems with these on Sixes in the past, but nothing a little file work couldn't fix. There should be some little bumps on the cylinder that fit into corresponding holes. If the fit is not perfect or it's assembled wrong, the ejector will ride on these bumps, producing exactly what you describe.

See the bumps here? If there's friction in the fit the ejector may be riding on them. They should go in all the way without any contact with the hole.
