Find a range close to your home, tell them you are new to guns and looking to get your cow license. They will point you in the right direction to obtain what you are looking for.
Randy said it right...
[QUOTE="Randy]First find some training at a place that will rent you a gun, try as many as you need, find one you like, fits you well, you shoot well, and is in your budget. No one on a forum can answer the question you are asking, we don't know you.

Shoot as many guns as it takes to find just the right one, once you do that practice, practice and practice some more. There are classes you can take to help you feel more comfortable and get better with your gun.
Good luck
