Dad’s got his finger on the literal trigger

Index finger looks straight to me, generally I see not a lot wrong with their positioning and grip on the guns in this picture.

Except for the fact that they are posing for a family picture with them - guns are not toys, they’re not accessories , they’re not decoration - their only purpose is being tools of destruction, handling them in any other way is improper to me.

So in the picture it looks fine but the whole premise of the picture is the improper handling of guns in the first place, any sort of discussion about the content of the picture should begin there.

Edit: Index finger straight next to the trigger guard is okay-ish I’d say, lots of caveats there, but resting your finger on the leading edge of the trigger guard (like the upper left guy) can lead to serious accidents by mistaking the trigger for the guard. Second guy from the left has better positioning of the finger but the one handed holding of a rifle while the other hand is free gives me the irks.
