Your outfitter can best advise you, but to me taking a can, even if legal, to a third world country ripe with corruption is just not something I would do. You can easily replace a rifle. Not so much with a can. Just my 2 cents.
You cannot take a suppressor into Mexico. You can't even take an extra scope anymore. I've made my last trip across the border to hunt. Not worth the risk of drama. A couple of months ago my neighbor was carjacked at gun point. Took everything he had. It's just not worth it.
