Security Six cylinder gap problem

I've got an old beater Security Six that I use while walking in the woods or for plinking. If I take it to the range and fire a hundred or so rounds of moderately loaded .38s the cylinder can bind. I think my cylinder gap is a little tight (.004") and the dirt and heat are causing problems.

So here's the question: can I ever so gently take some 600 grit sand paper to the forcing cone to increase the gap a couple thousandths? Or is this Bubba Gone Wrong?

Thanks,
pastorcurtis

pastorcurtis, I do think this is a "Bubba gone wrong" issue. The rear barrel face needs to be squared with the cylinder face. This would be nearly impossible with a file or sandpaper. A "facing cutter" is the right tool for the job.

.004" B/C gap should be just fine. The bind in the cylinder is more frequently from using too much oil on the ejector, ejector rod, and cylinder yoke tube. The oil draws powder residue and will bind up the cylinder. My suggestion .... field strip it and give it a good cleaning. When you put it back together, don't oil the yoke tube, ejector, or ejector rod.

Some ammo is worse than others because it burns dirty or there are powder flakes that don't ignite. You might try a different brand of ammo or if you reload, try a different powder.

Have had this exact problem caused by unburned powder flakes (probably Unique) getting trapped under the extractor star.

Thanks, gentlemen. I'll give it a good cleaning with special attention to wiping down the cylinder and head back to the range.

Send it back to Ruger and they'll overhaul it for free.

Security Six cylinder bind...

newbie here, just happened on this thread...

I have the same issue with a 1976 SS Security Six, .357mag. Cylinder binds after 50 or so rounds. Is it true Ruger will fix this issue free? If so, I assume it has to be sent from an ffl dealer?

Thanks in advance guys...Ron

rpludwig, If you look on Ruger's web site, it says that Security-Sixes are no longer supported. They have been out of production for 22 years. Likely it's not the gun's fault ... rather a poor cleaning regimen, too much oil, or crap ammo.

They're no longer FULLY supported, but they are still supported. They just don't have all of the parts for them (but have enough to really do a beautiful job on a gun, as I just recently sent my dad's to them and got it back, and it involved, among other things, replacing the trigger spring, the hammer pivot pin, the pawl, and the cylinder release button, and the rear sight blade).

Try cleaning under the extractor star. Should be no visible oil there and no unburnt powder.

My security six shows the same symptoms. After about 50 rounds it will start to bind, let it cool and it is fine. I found that it was the ejector rod unscrewing itself.

A common cause of cylinder binding in the Ruger Security-Six is this screw having worked loose.

Hmmm...I called them about a year ago and they wouldn't really even talk to me except to say that they don't support the gun anymore and suggested I contact numrich. Maybe I will try them again.
