........... I am going to suggest that rather than a 9, your first SHOULD be a .22. Matter of fact, a Ruger .22. Careful shopping, you can find a nice NEW one for about $300, and a good used one for less.
The habits, practices and skills you develop with a .22 will carry over into other firearms, and with budget being tight, you will shoot a LOT more with a .22 than with a 9mm.
I second that !!!!! That is EXACTLY what I did when I first started out. I got myself a M&P.22 and was able to shoot a lot of rounds for the money.
Taurus: 709 Slim
Stoeger: Cougar - 9mm
Smith & Wesson: M&P .22
I don't think these guns cost much, but I started with a Ruger MK3 and went to the Sig because I wanted to get the feel for a 1911.
I don't think a Ruger 1911 45cal is very expensive, but it is a good starter gun although it's not as accurate as the Ruger MK3 because it doesn't have the sights a MK3 has, but a good gun is only as accurate as the person shooting it. I know that to be a fact.
