Actually, half that price is good enough. Glock is just being Glock about it.
To me, it's too much to spend on equipment that gets smashed, thrown, and broken on a regular basis because of the intensity of the training. And more money doesn't really equate to "more rugged" once you get past the spring operated guns.
I spent $100 on my main Colt Commander (live gun, used) years ago. I cleaned it, changed out the springs, it's worked fine for years. Sure, I could spend $2500 on a Wilson Combat, and it would be really pretty, no doubt. But I probably wouldn't be as reliable as my old, clunky Commander, since all that extra money tends to go into hand fitting and tighter machining...which as we all know, actually reduces reliability when a gun gets hot, and that's not what I want in a self defense gun.
That being said, obviously Airsoft guns don't get hot, but those who have done some real Airsoft training should be able to testify that "accuracy levels" were not the issue. Yes, we want guns that run, and we want them able to withstand being dropped on the floor more than once. I just haven't seen an expensive Airsoft gun that looked like it would hold up to me throwing it on the concrete any more than a cheap one. And I don't own them to punch tiny holes in paper at 25-yards. Because of that, I invest in the reliable guns for $100-200, and then expect to have to replace them every so often.
Perhaps the new Glock Airsoft will be a true metal gun, but they had a sample at the SHOT Show this year and those who saw it said it wasn't any more impressive than the Korean Airsoft guns.
Hope I'm wrong, because we all could really use some hard to break Airsoft guns - and if they make one for $300-400, I'd consider it if I knew it would last me.
