Barrel / Cylinder clearence on a revolver.

I am curious about a B/C clearence issue on a new revolver of mine. I may have asked this before, I am not sure.
During the opening and closing of the cylinder, the cylinder lightly scrapes the barrel causing some minor scratches on the front side of the cylinder. Now, when the cylinder is fully closed it rotates freely and properly. This gun is new and has never been fired. Nothing appears to be bent or out of order. The B/C clearence issue is only of concern to me during the opening and closing of the cylinder.
The gun is a Taurus Total Titanium 38 special. I am calling the dealer about this tomorrow, but I wanted to get some input from the TFL people here as well. Any one have any similar experiences on their revolver's barrel / cylinder clearence gaps?
Thanks
 
The gun is bent. Either the crane or the crane pivot pin. May have come from the factory that way or a potential customer did the damage by whipping the cylinder open while looking at it at the store.

Back to the dealer with it and let them take it from there.

Sam....If I pay extra, will it get there yesterday?
 
Exactly what part of the pistol is the crane and crane pivot pin? I have checked over this gun, and everything appears correct.
I will be calling the dealer first thing tomorrow.
 
Nobody did it by flipping it open or closed. It came from the factory that way.

Lightsped, this is a common malady with new Taurus revolvers these days. Even Gun Tests has commented on the frequency of their Taurus samples having absurdly tight B/C gaps. It may spin freely now, but I suspect that if you fired the gun, within a few shots, the cyllinder would jam up tight as a drum once fouling is introduced. Take advantage of that wonderful Lifetime Warranty.

The frequency of silly lapses in Taurus quality control is why I tell people to avoid their revolvers.
 
Hi, Blue and guys,

If the barrel is scraping the cylinder, the gap is obviously a lot less than .004. I suggest a gap should be .005-.007. Any more can cause too much pressure loss, any less can cause binding from either fouling or heat expansion of the cylinder.

The frame need not be bent, although that is one possible cause. Taking a new gun back is a good way to go, but if that is not possible, anyone who can use a file can take a bit off the breech end of the barrel to get the proper clearance. Be sure to protect the top strap if a safeside file is not available.

Well, I was at a local gun store today and I saw a steel version of my Titanium 38 special. The steel model was also a Taurus 38 special.
Anyways, I asked to examine the gun and it too has the same issue with the cylinder scraping the barrel when ith cylinder is opened and closed.
Maybe the Taurus pistols are supposed to be this way? I know the S&W pistols aren't like this.
Any ideas? Anyone here have a Taurus revolver?
