Your budget seems to be under $900. which leaves a lot of choices to conciser. So if I had that much saved up I'd start with looking at the Sig's. They Have a couple nice 9mm's and .380's in the size you're looking for. Then I'd compare them to a Ruger .380 LCP and an S&W M&P 9mm Shield. Then try to shoot them and see how they fit & feel in YOUR hand.
The posters can make suggestions on what WE like but it's like buying a pair of shoes. You have to try um on to see if they fit YOU. I might like Billie-Bob shoes but, they don't fit you comfortably so you like Bob-Billie shoes.
So I'd suggest a 9mm or .380 Sig, 9mm S&W-M&P Shield, or .380 Ruger LCP < final answers
Good-Luck in your search I'm sure you'll find something to fill the void.
