Sader's,...you are on a budget right now. If I were you, I'd pick a good used, or new Nork SIG 226 or CZ 75 copy of the EE or from one of the sponsors in "9MM Parabellum".
When you have more cash, and can decide on what direction you want to go, 9mm, .40, .45. IPSC, handloading, etc etc, you can always sell the Nork on the EE, probaly for exactly what you payed for it if it was used to begin with, and upgrade to a finer made pistol. When I say finer ,I mean a Glock 17.
The 9's as cheap as it gets in bulk ammo without reloading. Well maybe the Tokarev with corrosive ammo, but I don't recommend that for your first pistol.
So a good copy 9 pistol for $300-350, plus bulk fmj ammo for around $14.00 for 50, and I see lots of bang bang in your future. My first 9mm, 30 years ago, was a German P-38, mismatched, and let me tell you, it didn't back down from any service pistol on our range firing NATO ammo! That makes me think maybe even one of those post was P-38's for around $350, is not a bad idea either.
Anyhow the point is, any of these won't cost an arm or a leg, it will get you double tapping, and after you're seasoned, and are outshooting the Nork or P-38, than you can sell, minimum loss, and buy a new or good used "Brand name

" pistol. That would probaly be made in Austria.
I didn't mention the .22 route. I had a Ruger MkII 5.5" Bull barrel, very accurate, very economical, and very boring. I know you want to shoot centerfire

,......... everyone does right????
