I am a surgical resident living in Los Angeles and I'd like to take up shooting as a hobby to relax and to train my hands and breathing to be more steady for surgery. Being able to use the weapon for self-defense would be nice, since I live in a bad area in LA, but I am pretty careful so I doubt I will be carrying it much. I doubt I will do much hunting either but it could be interesting. Most importantly, I am still paying off my loans so I don't have that much extra money to throw around though. I just have a few questions to try to get myself started though: 1) How much will it cost? For the gun, trainings, and license fees. 2) Should I start with a handgun or a rifle? Which ones do you think would be best? 3) What trainings should I get? And (for people in Southern CA) where should I take them? Thanks!
