It's not a gear snob thing to insist on the highest reliability in gun gear. The whole point is that if gear fails, it could directly lead to immediate death. At least that's the standard.
How real that standard is depends on the skill level and redundancy of the user. A lot of military and tactical training is all about backup plans, alternate weapons, transition drills, etc. Then the gun is supposed to support the concept by being absolutely free of any failure, and help the user with faster reloading, backup sights, cowitnessing, and ambidextrous controls.
Note that with insistence on reliability, the market takes opposite view to sell a redundant back up option. They want you to spend for reliability and spend because failure seems guaranteed.
It's all a marketing game pitched to sell gear. The average Home Defense encounter involves a handgun with no optics and less than three shots fired at less than 21 feet.
Any gun in HD is better than no gun, buy an optic that matches the other 99% of what you will use it for. Lucid, Bushnell etc all make good optics in the $200 range, and you get money left over for ammo. Training is more important than brand name or alleged reliability of military optics. They break, too, the light repair company techs see the blinking cracked and dead optics all the time.
Most Americans - well, well over 90% - never have a home invasion. It probably happens less often than the breakdown rate on midrange priced optics. Find a balance point, practice, and be happy you have Customer Service, because the Army doesn't. They have a big inventory of float optics and their own repair department - if it's not declared "disposable." They get around the problem with an issue in kind - because their backup plan is it WILL break, and have spares.
