Recently on a visit to El Cajon gun exchange, I saw a scope mounted 7-1/2" Redhaawk, identical to the one in my cabinet. I had purchased it there years before. The price was only $400 with a nice Burris scope, but I was told that it was available only to Law Enforcement.
The explanation was that California requires manufacturers to submit samples of every model for testing to become eligible for sale in the state every year. There are licensing and other charges to the manufacturer. Since the sale of some models are not sufficient to warrant the expense, the guns are no longer legal, although it was legal the year that it was brought into or originally sold in the state. Also illegal are 2" or shorter barrels, so the two new Smith compacts have a problem in that the auto is illegal while the revolver is ok. He said that in the future we eill likely see more 2-1/8" barrels!
This was explained to me there and then, by a guy that has been there for years, so take it for what it is worth!
