Security six lock up
« on: June 29, 2004, 06:26:18 AM »
I have a Ruger Security Six 357.  I have been shooting reloaded 38 wad cutters and factory stuff, about 500 rounds since I bought this gun over a year ago.  Two weeks ago it kept jamming on the same cylinder.  I could only quarter cock it and had to force the cylinder out with some force.  Cleaned the gun as best I could, but did not disassemble completely - not confident on doing that.  

Well last week it did it on the 2nd and 3rd full cylinder and then just every 4th or 5th loading.  Any clue what this could be?  It is always the same cylinder.

Sounds to me like you may have some dirt under the extractor. Clean it extra good and try it again.  KN

Cig,
Like KN said, You will have to hold the extractor rod out and hold it while you take a brass brush and clean the face of your cylinder off real good,
And you might run a brush through the chambers of the cylinder, If that don't stop the problem you need to get it to some one for some help.
Hope it come out ok. Good luck..........Joe...................

My Security Six was sticking on the same chamber.  Took it all the way down (it really is an easy design to work on - get the NRA expanded diagram and follow the instructions on disassembly - it was easier than the first time I did it without instructions (but I did do it!!!)).

First was the cylinder was filthy.  Lots of powder fouling accumulated over 8 years (I know I don't shoot much ;)

Second was the cylinder advancing finger was misaligned (the piece of metal that comes out of the frame and engages the advancing star on the cylinder).  I reassembled the gun 3 times before I got it right.  I still need to shoot it to make sure it's fixed, but I think it is.

Other option is send it back to Ruger and let them fix it.  The warrenty lasts a lifetime.

Well it did it again last night.  Locks up on the same cylinder initially on a live catridge.  Replace it with a spend one and it is fine.  Cylinder goes in and out and turns on pulling the trigger, but not with a live catridge.  Will not go in and gets stuck pulling the trigger.  Could the cylinder be out of square?  Anyway it makes no sense and I can't figure it out, so off to a professional.

Have you checked the primers on those reloads?  Any chance they are not fully seated?  Shouldn't only hang up on one particular cylinder if that is the problem, but its a thought.  Otherwise, I agree with previous posts about thoroughly cleaning cylinder, extractor star, chamber mouths.  Maybe some bullet lube is gunking something up, or a shard of lead.  You might have a local smith look it over before taking the time to send it to Ruger.  Good luck.  My security 6 just keeps on going.

I haven't cleaned the gun since I fired it Wednesday, but I do clean it very well.  I also take the lead out of each cylinder with a lead remover- rod with brass patch.  I will look at the reloads and see if dropping in a factory load will let the cylinder rotate and I will clipper the reloads as a comparison.  

If it looks like that is the issue I will run a box of factory 38's through it and see if it hangs.  If not then it is a reload issue and I will to look into that.  Thanks for all the advice.  

This gun was bought highly modified (Bull Barrel and target smooth trigger) so I don't think sending it to Ruger vs. a local gunsmith would be a good idea, would it?

I have a couple of security six revolvers and had a similar thing happen to the 4".  The cylinder pin is screwed into the extractor with a left hand thread and held in place with an inside star washer. The rod had backed out a turn or so and that lengthened the whole assemble causing it to wedge in the frame when a loaded cylinder was closed.  It took several tried before I got the washer centered in the cylinder.  The washer is there to retain the spring that pulls the extractor toward the cylinder.  It can tighten off center and bind the spring or the inside of the cylinder.
Don't know if this is your problem or not, but that was my experience.

CIG, I'd bet the farm that RadioTech is right. I've a Security Six that i've fired jillions of rounds through and it's done precisely the same thing. Just screw the cylinder ejector rod back in (left handed threads) and I'll bet your troubles are over.
Good luck.
