First check the Head Space and B/C gap, I prefer a .003" to .006" gap. Open it up and throughly clean the internals and check for any burrs. Then clean and check the cylinder axle, if these checks and cleaning don't resolve the problem I would send it back with information of any things I found during the inspection and cleaning.
If you bought it new within the last year call customer service and ask to send it back for service. You may have to conjole the Customer Rep. a little bit to get them to cover shipping both ways if you have had it less than a year.
I have been hearing that the repair turn around time has been getting better. A couple of years ago it took five weeks to get my 617 repaired and back in my hands, now I am hearing some times as short as two weeks.
There is a very good thread on here about disassembly and cleaning Taurus revolvers.
