I would recommend that you start with a .22 DA, they are cheap to shoot, aren't punishing, can be shot single action, and make a great survival tool. A .38, .357, or larger are great for killing larger game, but are way to powerful for small game. You will also pick up bad habits shooting these as your first handgun, mainly flinching. I have a .45 acp, and 38 special +p, and can shoot both accurately, but am in the market for a .22 handgun as well for the same reasons shown above. It costs me ~20.00/box of ammo for the .38 and .45, with a .22 I can shoot all day for the same cost. I also want to teach my 10 year old daughter to shoot. She is slightly too small for an adult gun, and I don't want to purchase a youth gun, since she is my one and only child the gun will be useless after she out grows it.
