You have listed a pistol, rimfire rifle, and centerfire rifle. I am unfamiliar with the centerfire rifle, although a high velocity rifle would be nice to have for target, defense, and hunting if needed. Check out the thread 'gun advice' to see comments re: the 10/22. It is a well liked 22LR rifle. It also can be used for the above tasks.

The SR-9 is an OK pistol. Ruger is better known for their revolvers than their automatics. The 17 rd. mag may limit you in Cal., however I'm sure 10 rders are availible. If it was a pistol I was looking for, I'd look for a used Glock 19. That should be in your price range. I'd do more research, ask around, ask friends, friends parents, co-workers, and shoot their guns before I made a choice. Hope this helps.
