cobain 187:
The right pistol for any individual is subjective and personal. This isn't intended to be a smart a$$ remark, but the right pistol is the one that you can shoot best. I can shoot some make and models easily while with others, I would be better off using them as a club.
You need to shot several weapons in a variety of calibers. Beg steal and borow and shoot as many weapons as posible. If there is a shoting range, or gun club near you, there are many people who will allow you to shoot their pieces, especially if you volunteer to buy the ammo. IMHO this is a must.
CALIBER:
Next, how much pistol shooting have you done? The best stoping power weapon will do you no good if you cannot hit the mark with it. I generally recomend a 22 as a starter pistol (inexpensive and good to learn basic pistol marksmanship). Again, thats where shooting a variety of calibers comes in handy, as this will tell you what you can learn to handle (emphasis on learn).
MAKE AND MODEL:
You will get a lot of good responses here, based upon the writers preference, and what works well for them. You should pick one that has a reputation for reliability, and you have a lot of good choices. Do you want 1911, SA, DAO, or SA/DA. Again, thats why you need to shoot several makes and models first.
