It probably has to do with the State fees, like your DROS. You get jacked by the state everytime you buy a gun, first finacially, then their waiting period. In that environment it makes more sense to keep what you own.
The drop test has hit handgun sales hard, the used handgun market in Cali is terrible. First you have to find one, then agrue with the dealer why it justifies a 20% premium.
I spend a lot of time on assignments in California, and pop into the gunshops down there reguarly. I have yet to find a good price on anything, the best that happens is "fair" on occassion. An example is Yugo SKS's are going for over $250 there, I was in three gunshops two weeks ago and that was the best price. Considering I just paid $135.00 for one in better condition I wasn't impressed.
Another example is I had done some hunting for a Pre 53, model 70 Winchester. After I did finally find one in Kali, they wanted almost $800 for it, needless to say I passed. On top of that I would have to pay to ship it out of state.
I bought one in better shape for $500.00 delivered. Pretty much a no brainer on my part. I went through the same drill on a BRNO rifle way over priced. I have gotten so I really don't bother looking anymore, cause it seems to be a waste of time. If I bother looking here any more it needs to be something rare, that I am willing to pay the premium on.
