Those in CA may have a long wait for the Shield, as they do not have either a magazine safety or a loaded chamber indicator. Ditto to microstamping. The Shield does have the viewing port to see the loaded casing, but this does not qualify as a loaded chamber indicator. When the sales of the Shields finally slow down, S&W might make the modifications necessary so that the Shields can be sold in CA, NY, and MA.
The California gun law is as follows:
"In California, as of January 1, 2006, an “unsafe handgun” will include any pistol that does not have either a chamber load indicator or a magazine disconnect mechanism. As of January 1, 2007, handguns in California will be required to have both a chamber load indicator and, if they have a detachable magazine, a magazine disconnect mechanism. When this provision takes effect in 2007, California will be the only state that requires both a chamber load indicator and a magazine safety disconnect. As of January 1, 2010, California will require that all new semiautomatic pistols be equipped with microstamping technology in order to be sold in California."
