Dude, go for an XD series Springfield. I have owned firearms since I was 9 years old, I am 29 now. I curently own over 100 firearms, I have them all, Glock mods 23, 30, 22, 17. Beretta 8045, 92 F, H&K, Para, Kimber.
But as far as you looking for a first gun, The xd is awesome. You can get it in .40, 9mm, .357, I own all 3.
I would recommend the .40 cal, 10 rounds. My buddy is in the FBI and they are all switching over to the XD, as well as the Secret Service, most State Police, and even the Pope's Security. They are shooting the shit out of the Glocks, and are no doubt the best polymer semi auto on the market. An XD should cost you between 5-600$, i got all mine for 515$ each.
I have a concealed carry permit in PA where I live, and I carry the Xd .40.
If you have any ?"s please email me, I am always happy to help anyone with choosing, locating, and finding the right gun.
God Bless America! and help protect our Second Ammendment Right!
