MrGunsnGear had his accidental discharge recorded. His trigger seems to have some problems. Skip to 1:47 and you can see the incident. This is another example that it is important to point the gun at the safest direction.
The old saying is that there are two types of people - those who had a ND and those who will. It is not about accusing shooters, but lapse in judgement can lead to NDs.
