S&W revolver dry fire ringing

[pinger]

I have a S&W 66-8 (current issue) that has a ringing sound when dry firing. Sounds like a high "ting" sound. This is my first revolver to do that. I have over 10 S&W revolvers that just go click. Some are as new as the 66. This is my first revolver that goes ting.

I spoke to another person who said his 586 does that. I also tried a new 66-8 in the store and it tings.

Anybody else notice this sound?

Sound of the transfer bar?
I'll try it when I get home.

I was so distracted about listening for the 'ting' ringing sound during a dry fire exercise
that I forgot to check to see if...Geez! My ears are still ringing.

I suppose having a frame mounted firing pin as opposed to hammer mounted could make a difference - my experience with new model S&Ws is very limited. However on older Smiths that noise sometimes resulted from a less than full powered hammer drop. Meaning the strain screw was backed off or mainspring lightened. Using the Wolf reduced power mainspring, sometimes happens with it too.

Yes, same gun (66-8) with same sound when dry firing with snap caps.

Thank you. It is the mainspring but there still is a difference from my other Smiths. The screw was backed off about a turn. When tightened all the way, it still tings but a sharper shorter higher pitch ting. With the grips off when I touch the mainspring while dry firing, my finger absorbs the ring vibration and it just goes click like all my other Smiths. The 66 just comes with a musical mainspring.

I experimented with a foam earplug. When the earplug touches the backside of the mainspring, the ringing is eliminated. On the frontside the ringing continues. The higher up the mainspring, the less pressure is needed. The higher earplug position near the hammer does not touch the mainspring at all when cocked and barely touches after firing. It gives the satisfying click.

Compound bows and tennis rackets have vibration dampeners that make an actual difference during use. This issue only makes a difference when dry firing. I don't know if anyone else gives a hoot about this but I feel better now. Thanks.

Would be interesting to see if you replaced the mainspring w a better one? The one that comes in the Wilson Combat spring kit seemed much heavier duty vs. the OEM one when I installed the kit.

If it works and doesn't interfere with function or reliability, I guess that's what counts. If you sell the gun and leave it in - I suppose it will lead to some head scratching.

May be that a bit of duct tape around the middle of the mainspring would accomplish the same result.

The mainspring does look a bit flat in those photos, which is usually associated with the strain screw shortened or back out. I'd expect a little more curve to it. Any chance the screw was clipped and a lighter trigger return spring dropped in - a 13# or so?

It’s so funny you bring this up. I have noticed the same thing. I have a 66-7 that makes the ‘ting’ and a 66-1 that doesn’t. Also, I have a 686-6 that makes the ‘ting’ and a 686-4 that doesn’t. The obvious difference in both cases to me is the transfer bar.

You don’t notice the difference when they are loaded. ;-)
