I know that this is a little off what you’re asking, but my suggestion for a first gun would be something in a 22 LR. Learn to shoot before you buy something to carry.
The main reason is price of ammo, Box of 525, 22 LR for 21$ at Midway. Cheep 38 special at the same location has 50 for 19 $.
Start with a 22 and make yourself a better shooter for little money. Start with A Ruger MKIII which has a SRP of 379$. It’s one gun you will never be without once you own one.
