Just bought a .40 and a 9mm.
Are you a woman? Are you European? jk
Handgun ammo hasn't gotten stupid like the rifle stuff. Is see it on the shelf in plenty of places. For plinking, any cheap brand is fine. Even steel case.
For personal defense, Hydrashok is fine. I like heavy bullets on .40, but that's just me.
Remington Gold Dot is VERY underrated. So much so it's hard to find on the shelf. Hornady TAP FPD is good stuff too.
