Hey Trey, I have a flawless G26 9mm, sub-compact, 3 or 4 mags, all with pinky ext, night sights, etc. that was one of the firearms I carried when I had my CHL. I have to pay for an engagement ring so I may be able to let it go depending on ur budget. You said $500 was more than you were wanting to pay, so hit me up in an IM and let me know what all you are considering.
I was 23 when I got my CHL and spent COUNTLESS hours in multiple forums researching the differnt laws across the states, different calibers and opinions, and it did help narrow my search, but nothing helped like actually getting the chance to practice with what I thought I was interested in getting. You can ask 10 different people about carrying and you will get 10 different answers and philosophies. It will depend 100% on what you feel comfortable shooting and what you personally like as a firearm. I had the budget for an HK, thought they looked cool and all that jazz. Turns out they dont fit right in my hands so I now have other stuff. Lots of factors to consider.
My $0.02
