In regards to the new California law, Senate Bill 15:
The statute specifies a 600 round test to include the first 20 rounds without, "a malunction that is not due to a faulty magazine or ammunition." This is from Chapter 248, Section 12130, subsection 1.
In addition the firearm must be submitted for testing by the manufacturer in the configuration it will be sold in. See chapter 248, section 12127a. This means that the Glock would not be legal if modified aftermarket to bring it "up to" specs. The Glock will not pass anyway because it, "Does not have a positive manually operated safety device, as determined by standards relating to imported guns promulgated by the Federal Bureau of Alcohol, Tobacco, and firearms." This is chapter 248, section 12126b1.
One final clrification, the correct term used is "Unsafe" not Saturday Night Special. This is a significant point because as usual LE is exempt from this law. A LE officer can shoot you with a Glock pistol, but you can't use the identical weapon because the State of California declared it "Unsafe". Many LE agencies were against this wording because of the liability lawsuits sure to come by their officers walking around with "Unsafe" weapons on their belts.
There are other equally insane and illogical provisions in this law.
