For your first handgun those are excellent results! Congratulations and keep practicing. Also, try different brands and weights of ammo - All guns have their preference for ammo, you just need to experiment a little! If you shoot a lot you will probably want to get into reloading - this will save you tons of money and allow you to customize your ammo for your shooting pleasure.
