Question about DIY narrowing of the cylinder gap on Security Six

    The cylinder gap on my Security Six is .008"....a little more than I care to have.

    Is it possible to narrow the gap by placing a SS shim (similar to an endshake bushing) in between where the crane (forward of the cylinder latch plunger) abuts the frame just above and ahead of the trigger?

    I was thinking a .003" thick bearing with a .345" ID and .460" OD might do the trick to bring my cylinder gap to .005".


    Perhaps a .004" or .005" thick bearing between the crane and frame and a .002" endshake bushing INSIDE the cylinder?

    Am I barking up the wrong tree or would this work? The only snag I can think of is perhaps the thickness of the bearing would make the cylinder hard or impossible to shut?

    I'm fairly ignorant when it comes to revolvers, so any help would be appreciated!

    Here's my personal take on the matter - send it to a good gunsmith and have him do it. I realize the desire to do it yourself is strong, but, this is one of those things that it's better to let a professional handle. Just MHO.

    Old Fuff? TOGGLELOCK? Is there an expert in the house?

    .008" is well within the acceptable gap range.

    I'd leave it alone. The gun won't shoot any better, or generate enough of a difference in velocity to make the effort worthwhile.

    Leave it be.

    You have to take headspace into consideration before you can shim the cylinder forward.

    If headspace is near max now, moving the cylinder might result in mis-fires because the firing pin will not reach as far.

    I'm not failure enough with Ruger DA's to comment beyond that.

    If I was to consider a DYI, I would sure get this book first.

    Thanks for the responses. I hadn't thought about the headspace issue.

    i've always understood that the correct way to narrow cylinder gap is by setting the barrel back into the frame. that way you don't mess with the headspace or the hand engagement
