Contrary to what you might expect, review guns are usually pulled out of inventory, not cherry-picked for function, or appearance. I prefer it that way, because then I review guns representative of what you’ll get at the store. But, it means I wind up with some lemons, too; a manufacturer once sent me a gun that discharged when the action closed. However, when I receive a lemon, I’ll return it for another gun. In a review, I would make note of the fact that I sent the first gun back because it didn't work. In the case of the slam-firing gun, I sent it back, it came back to me "fixed," and it fired again when the action closed. I sent that one back, too, and decided, in that case, two strikes were enough.
