My wife was getting nervous because of the kids as well a couple of years ago
She wouldn't believe the kids are not strong enough to rack the slide on a pistol or even pull the trigger in a DA gun.
So I took my guns, showed my wife they were all unloaded and tried to instruct the kids how to use them.
They were not able to even pull the trigger on my revolver, not to mention rack the slide on my 1911.
After she was almost convinced, I gave her my 1911 and told her to rack the slide, she found it very difficult.
After that she didn't bother me anymore.
And regarding the rifles, they were all to heavy, the only danger would be for the kids to drop and smash their toes.
