Yup right you said when a gets used to such thing it doesnt bother anymore then....it is not actually the gun it is the person holdung it...this really sucks...even if the gunfire is heard from the surrounding ...i have seen a situation like this....gunshot was heard from the nearby place and i was sitting with my neighbour grandma...she is too old ...but when the gunfire struck ..the loud noise nudged the grandma to the minor heart attack....she almost got killed ....heart attack and at such old stage...but thanks to lord she was hospitilized and was fine after few days.....this thing really sucks.....
