You really have to keep an eye on these guys.
SB489 (Scott - Dem) Semi-Auto Handgun Bill - Requires all newly-designed semiautomatic handguns submitted to CA DOJ "safety" testing after January 2006 be equipped with a loaded chamber indicator and/or a magazine disconnect mechanism. SB489 was massively amended to achieve passage - the author had to agree to serious limitations on the bill's implementation and effect. While originally targeting all semi-automatic handguns manufactured after 2005, SB489 was amended to affect only newly-designed semi-automatic handguns. All existing semi-automatic handgun designs, as well as new designs which are submitted to CA DOJ safety testing before 2006, are now exempt from SB 489.
