Just got my first new gun for the year 2010, a Taurus 990 4-inch stainless, 24 hours ago, from PSS. $379 + tax. Haven't fired it yet, but I think I noticed a problem. It works fine (dry fire test using empty cases) in SA, the cylinder locks up whenever the hammer is cocked. But when I pull the trigger very v-e-r-y slowly in DA, like from start pulling the trigger to hammer drop taking 5 to 10 seconds, for some chambers, the cylinder latch does not lock into the designated cylinder notch (hope I got these terms right)...
When I pull the trigger in DA, the latch goes down, the pawl comes up engages the ratchet, the cylinder starts turning, then the latch comes up, rubbing the cylinder as it turns. For some chambers, the cylinder will stop turning when the latch locks into the notch with an audible click, then hammer will drop. Perfect. For a few other chambers, the cylinder stops turning, but there is no click. After the hammer dropped, I kept the trigger depressed, I found that the cylinder was locked up by the latch when I tried to turn it by hand. So apparently the hammer impact rocked the cylinder and caused the latch to fall into the notch. But for yet some other chambers, the cylinder would stop turning, no click from the latch, hammer would drop, with trigger still all the way back, I could manually turn the cylinder some more, and hear the latch click into the notch...
I believe this means the chamber didn't line up with the bore. If I'd fire a live round with those chambers in DA, the bullet wouldn't be able to enter the barrel, and I'd have KB in my hand. I've only got two revolvers so far, both Rugers (SP101 and Redhawk). Both would lock up before the hammer drop in DA. The Redhawk is more pronounced, the latch will click in long before the hammer drop. I'd like to confirm with someone who's more knowledgeable with revolvers, that this is a serious problem, before I start calling Taurus on Monday...
Thanks!
