My very first gun period was a Taurus model 83N (Nickel).38. It had every defect possible and still actually shoot. The timing was off a mile, the action was "crunchy", the front of the cylinder wasn't straight, causing the gun to lock up due to heat expansion after a few quick shots, and the rifling was so bad it would be loaded with lead after a single shot! The nickel plating was done very well, at least they got something right.
I sent it back to Taurus, twice, and they fixed the cylinder problem, and partly fixed the timing issue, it only slightly spit lead after the second trip down to sunny FLA. They also nicked the gun up both times. They refused to admit that there was anything wrong with the rifling, even though it came back from them so loaded with lead it took me a long time to chisel it out with my trusty brass screwdrivers. I talked to some guy on the phone and he remembered my name, and the gun, but claimed there was nothing wrong with the barrel. I got PO'ed with him finally and hung up. I ended up selling it to some guy at work for far more than it was worth, and bought the first DW Model 15 I've owned, something that actually could shoot as many shots as I wanted to shoot, and I could trust my life with. I haven't really even seriously thought about buying another Taurus since then, but I recently shot a 24/7 Pro 9MM and really liked it, so I was looking for one and found one at a semi local gun shop.
It was a nice gun, and even though I had the cash, I passed on it. A friend of mine bought it, and it's been nothing but a headache since. It runs, then doesn't, and one of the followers in the mag cracked too. If you use a brand of ammo it likes, and the thing is perfectly clean and lubed up, it will (Usually) go though two boxes of WWB in a row. Any more, and it's iffy at best. Taurus did replace the mag though. It seems to be getting worse as it passes the 600 round mark. The store wants to send it back to Taurus, the gunsmith owner there thinks the barrel is out of tolerance where it locks up into the slide. It does seem really loose to me, not at all like the one I shot that had at least 3000 rounds through it, that one was great.
I saw a couple of used 24/7 Pro's on auction sites, but I'm spooked.
