Is it possible to get a handgun in california thats not on their little "list" of approved guns?

I really want a little beretta bobcat, its a 22lr. California only allows the beretta tomcat which is a 32. Can I buy a bobcat at an online store like budsonline and have it shipped to my local gun store? And they have guns at my local store that are on consignment, what does this mean? I figured it was only for law enforcement to buy ?
