Last I heard there was only about 2,000 permits TOTAL in all of California. I have heard they basically go to state officers who are not issued pistols, like an officer who deals solely with Fraud, and people who handle LARGE sums of money on a regular basis. Things like handling gem deliveries at jewelry stores or payroll deposits for a large company. I have also heard that even then it is hard to get it.
You need several things also. Recommendations from several neighbors, proof of residency, detailed portfolio of all confrontations with police, etc. They really don't mess around with them, and something like "I feel unsafe in my neighborhood" won't get it.
Remember, it is legal to carry a weapon openly on a hip holster, so you have to prove that you NEED to have one hidden. The whole process costs almost $300 after classes and fees, and another $50 or so each year to renew it.
