I'll probably rustle some feathers with this, but...
IMO, it's rather like Harley Davidson motorcycles. At one time...they had a product that was very capable, and was superior to other company's products. Then, their product attained "cult" status, and the company (Harley Davidson/Colt), whether intentionally or just because of certain market conditions at that time...began to rest on their laurels. They began to churn out products that were not up to their original standards, but many people continued to buy their product...purely because of the name and status of the company. At the same time, other companies began to produce products that were nearly as good/every bit as good/sometimes superior to...the "cultish" company, at a much more economical price. Many buyers, especially people who were "new" to that product, or just either could not afford the Harley/Colt, or made the decision that the cost was not justified...purchased their products from the newer companies, and were (generally) completely satisfied.
However...due to the dedication of the more hardcore enthusiasts, the Harley/Colts continued to sell at high prices, particularly the earlier models, which really did have something "special". Because of the fascination of the hardcore fans, and the cult-like status...even amongst more ordinary users, the cycle continues. I hope that made sense.
So, again...IMO, no...the prices are not justified. Well...not in terms of actually using the product (gun/motorcycle/whatever). However...one could make the argument that they *are* worth the money, if for no other reason than that they seem to continually appreciate in value. It really is all about the hype. But...if enough people buy into the hype, your investment will pay off. Also, of course...you do enjoy the pleasure/status of ownership, even if you don't shoot/ride it much, or at all.
Back when I was working...I was the guy who everyone knew as "that guy (or maybe "that idiot") who rides his motorcycle every day". I was riding a Triumph, a BMW, and 2 Kawasakis (on various days, not all at once...thank you very much!)...and I would frequently have guys walk up to me and ask about riding, and then say something along the lines of, "Yeah...I'm gonna buy a bike, and start riding too". I'd tell them that was cool...it's fun, they'll enjoy it. *Then* they announce that they've been saving up (usually for many years) to buy a Harley Davidson. Well, that's cool, I say...how soon will you be getting it? Oh...they still need several thousand (like...10) more. I say...why don't you buy something more affordable, for now? Get a used Honda, or Kawi, or whatever...ride it and enjoy it, while you're saving for that Harley? No...they have to have a Harley. "Gotta do it right...only ride "the best". Fine.
A year or two goes by, and I see them again. "Got that bike yet", I ask? They look rather downcast, and sullenly reply, "No...still saving. Something came up, and I had to dip into the 'bike fund'." So...they *could* have been riding all this time, but they'd rather wait...get the cult-status bike.
Anyway...that's my take.
