Where do we start?
I guess with the bad finger discipline? The female totally has her finger on the trigger. At least the guy is keeping his trigger finger on the gun frames – and not pointing his weapon at the photographer.
The next thing I would point out is that while I love guns but I don’t see any reason to bring them to my wedding shoot. (Get it, I made a funny.)
If you want people to feel more comfortable with firearms you need to stop stuff like this. Be responsible. Act responsible. Follow safe gun handling precautions.
