If you have a gun that doesn't work properly, get it fixed. How hard is that? All mechanical devices are made within a range of tolerances, and are subject to wear and failure. Swapping out a Remington trigger doesn't require a degree in engineering. Remington rifles are safe to own and use and always have been. But its the responsibility of the owner, to ensure his rifle is in good working order, and if he detects a problem, its also his responsibility not to use it, or allow it to be used, until the problem is addressed and resolved.
Of course this discussion deflects us from shining a light on the real problem, safe gun handling. Of all the safe handling rules you can follow, be it 4, 10, or 1000, the one that matters most is muzzle control. You can do everything else wrong, but a negligent discharge injures no one, provided the rifle is pointed in a safe direction. Fail to control the muzzle, and you might be tempted to blame others for your negligence, that results in the injury or death of another person.
