For just about 16 years now, some variation of the Trijicon RMR red dot sight has set the durability and ruggedness standard for rifle and pistol optics.
There are lots of red dot sights on the market — they’re nothing particularly new — but considering the greatest source of resistance to adopting the “new” way of sighting a handgun is the “it’ll just break at the worst possible moment” argument, there’s a lot to be said for one where the primary feature is not breaking.
In fact, I’ve (deliberately) thrown, banged and smashed them. On one occasion, when challenged by some Trijicon engineers, I zeroed one for 15 yards, unloaded the pistol, flipped it upside down, and proceeded to smash it against a nearby 2×6 piece of lumber as hard as I could. Not only did it not break, it remained on. And not only did it remain powered on, it maintained its zero perfectly.
So, in my book, while anything electronic can fail, this particular setup falls into the extremely low probability of failure bucket. Do your part and make sure to proactively change the battery every New Year’s Day, and you’ll be good to go for a long, long time.
