Do I have a problem or not?

[pyth0n]

I recently bought a Taurus 856UL, (I know, mistake #1) & found the when the slack/free play is taken up in dbl action mode (no other part of the action moves), the cylinder unlocks & can be rotated in both directions.
I sent it to Taurus, 53 days ago & they still haven't logged it in.
Since then I found my LCR, & Security Sixes will do the same thing. I have only seen this happen in Taurus revolvers, going back 20+ years. I never suspected the Ruger's to do it & until the Taurus, never thought to check. Never had any function problems.

Sounds like your problem may be how you're doing the function check. Correct check for revolver is trigger fully pulled, hammer down as if it's just hit the firing pin.

I have a Taurus 856......it's been very dependable. Have no idea of the round count. I have actually been carrying it quite often lately and my 45 M&P Shield has been sitting in the safe.

As for your observation, I don't seem to follow what you are saying or trying to accomplish? I just tried to create what you are seeming to say with a Taurus 856, Security Six, GP100, and a S&W MOD19. All are rock solid tight, no turning of cylinder nor will it release at anytime during the DA trigger pull or after hammer falls and trigger is held back.

I know how to perform revolver function checks but I can't follow what you are trying to say. Maybe I'm slow.....

Really simple. If I move the trigger 1/16" to, I guess what is now referred to as the wall ( just taking up the slack), the cylinder stop drops down & allows the cylinder to rotate freely in either direction. No other part of the action has yet moved. I was not doing a function check to test lock up, but to check timing.
I found this years ago with Taurus 66, in this case when if the cylinder was wiggled & without touching the trigger or hammer, the cylinder would unlock & be free to rotate.
This video show a similar problem.

Not doing the function check, but timing. The bolt unlocks early, before the hand or hammer move.
Here's a video of something similar. In this case he just wiggles the cylinder. In my case, just taking up the slack in the trigger, drops the cylinder stop.

This is what's happening.

Now I understand. The video in post #6 shed more light.

This is normal operation for a revolver (post #6) and does not interfere with reliability. It is the design.

The guy in the youtube video most likely had a defective revolver.

If you sent your revolver back just because of that (posy #6) Taurus is going to send back and most likely say the revolver functions as needed.

That's what I suspect.

I check revolver timing by slowly cocking the hammer in single-action mode. Then I check to see if the cylinder rotates far enough for the cylinder-stop/bolt to engage. I cock the hammer very slowly to prevent inertia of the turning cylinder from rotating it into the lock position. I am checking the mechanical function.
With a fast pull of the hammer or pull of a double-action trigger, inertia will rotate the cylinder to lock-up and conceal a timing issue caused by wear.

I’ve had a few Taurus 856 and have found nothing wrong with them. I like that they are 6 shot, I prefer the solid steel stainless to the Ul, and I like that they are available in 3” barrel. Mine have functioned flawlessly.

Sorry for the delay. Never got a notification.
Thanks for the input.
It's a new gun & the cylinder locks up fine, before the hammer is fully cocked in single action & when staging in dbl action .
I was concerned with it unlocking just taking up the slack in the trigger & before any other part moves.
Any way after 91 days I got it back from Taurus. In one sentence, they said it was repaired, in the next that they found noting wrong. It shoots better that I can (need to retrain myself in revolver).
Interestingly, because several members said it's not unusual, although infrequent, I checked my other revolvers. Seven of 9 Sec. Sixes & six, Speed Six, & LCR unlock like the 856UL. Taurus titanium .44 Spl., GP 100s, Colt, & S&W don't do it.
So I guess it's one of those things to live with.

This isn't the first Taurus I've come across with cylinder lock problem.. Two before & many years ago working retail, a customer bought a model 66 Taurus & brought it back because the cylinder would unlock by wiggling the cylinder. Trigger & hammer not touched. I checked it out & sure enough it did. Manager said to exchange it. Took another out and fiddled with it to make sure it was okay & it also unlocked & rotated without touching the trigger or hammer. (I posted a vid of an owner show his did it the way I described.)
Customer opted to exchange it for a GP100.
See #11 for the rest of the tale.
Thanks.
