100% Fuddlore. Some folks give too much credit to law enforcement without realizing the cost in manpower, court time, attorney time, expert time and costs, and whatever else it would take to actually get someone in trouble for modifying the trigger spring on their CCW gun. Seriously, nobody is going to notice whether it's 3.5 or 4.5 pounds (or whatever), and nobody is going to disassemble your firearm after an incident to test the trigger spring to see whether it's stock or not. If it ever happened, it could happen in a product liability case in which there is an alleged defect in the gun. Modifying the trigger spring to be extra light is a 1 out of 10 on the scale of firearms-related wrongdoing; the justice system has much bigger things to deal with than whether your CCW gun is unmodified. A use of force incident involving a CCW is already rare, which means an enforcement issue on legal components would be exceptionally rare, if it ever happened. Keep the components legal in California, that's the only legitimate restriction and many agencies understandably have that in their policies. Everything about modifications is CYA from the issuing agency-- don't forget that there is a clause in your application that you will defend, indemnify, and hold harmless the issuing agency in the event someone sues them over your use of the CCW. So it makes sense they would state they prohibit modifications in order to give them yet another out on suits against the county for negligent issuance of a CCW or whatever some lunatic criminal will claim if you shoot them in self-defense. Sorry for the excess passion, I just dislike dumb policies and I don't think people should have to follow other than the actual law or regulations. The discretion of the local agency is limited, which is sure to be tested in court at some point whenever the first person to try it does a writ of mandate to get these turkeys to fully comply with the law.
