Went shooting my M9 today and can't figure out what is going on. I'm fairly new with a handgun but I shouldn't be having the trouble I'm having. I set up a small target about 30 yards away and I hit all around it. When I tried to compensate one way or the other I messed up even more. Any shooting advise would be appreciated. I'm also having a misfire every 10-15 shots. Pull the trigger and nothing happens. I have to eject the bullet in the chamber and reload a new one to shoot again. Is there a maintenance issue here? The gun is brand new by the way.
