Might want to try shooting at pop cans with your airsoft pistol to improve your shooting skill.
Here a link to a Utube video:

If you turn up the volume, you can heard the 'cronnk' sound of the hits made as the gun is pointed and the trigger pulled. There are 7 out of 7 hits in the video. The distance was about 12 feet.
Here's a pic of the gun used. Not pretty but gets the job done.
And here's one of a recently acquired and modified rig.
