Effective ban on new handguns in California
Chuck Michel reports it here. Essentially, (1) microstamping of firing pins is now mandatory, but (2) it adds to the cost of manufacture and (3) given the current demand for firearms, why bother making a special model for California?
My memory may be off, but as I recall the law only became effective if the microstamping technology was not covered by patent. The patent holder waived the patent, but remains the only firm with the equipment to make the firing pins, so its patent monopoly just became an economic monopoly.
