The 'Dead Man Down' star - who has been sober for eight years - revealed his new movie has made him think a lot about gun ownership and he would never want to own a weapon in case his life ever spun out of control again.
The 36-year-old Irish actor told the MailOnline website: "I wouldn't trust myself to have a gun. What if I got drunk again? What if my heart is broken and I go crazy for a bit, or, even worse, what if I forget to lock my gun away somewhere safe and someone has an accident? I forget my car keys all the time, so why not that?
"Americans say: 'Oh, but it's our constitutional right, we're all grown-ups, give us guns.'
"Well, don't give me a gun, because I'm a human being!"
Colin - who has a nine-year-old son, James, with model Kim Bordenave, who has Angelman Syndrome, and a three-year-old son, Henry, with Polish actress Alicja Bachleda-Curus - also revealed he hopes to scale back his career in eight years.
He said: "I'll be 45 then, and I don't want to be making films back to back.
"People working on films miss important things. They miss weddings and funerals, and some of them even miss the births of their children. It affects their marriages. But there is another life out there.
