There are some valid concerns about the Remington trigger. However, now lawyers are involved it is hard to sort the fact from the fiction. Lawyers get paid to distort the perception of facts, and they are good at it.
The short story is that there is one component of the trigger that is spring loaded and needs to follow with only spring pressure. If it hangs up due to low spring pressure (user has adjusted the pull lighter), or crud (user has not cleaned the trigger), then it can hang up and become unsafe.
I have a 1960's vintage Remington 700. After it sat unused for a number of years the safety did kind of seize up. I cleaned it and the function returned to normal. The pull which has never been altered from the factory is as it always been, very crisp and 2.5 lbs. I like it, and believe as long as I keep it clean, and away from lawyers, it is a safe gun.
The new Remingtons are another matter. I see reports of high trigger pull weight, and less than great accuracy. I frankly would not buy them. Savage has blown them away with their AccuTrigger, solid actions, self aligning bolt head, and heavy near target quality barrels. No more Remingtons for me.
