I have not yet shot this particular one, but my previous 21A always functioned flawlessly. Back when I had it, CCI Stingers were still fairly new as was something from Remington called Yellow Jackets. I don't recall ever having any issues with it. When I bought this current one, the gun salesman, a retired law officer, said one saved his life back in the early 90's when he had it as a backup gun. He stated the same, that he never had a problem with it consuming whatever ammo he put in it. Given the choice, I probably would have gotten the stainless. I traveled nearly 2 hrs to get this one, as it was $110 less than the local gun store. I was able to get this one on a military base, where the Exchange sells guns, with discounted prices and the added benefit of sales tax.
