The next day I went into work and sat down with a trusted senior Mexican manager. I looked at him and said, "I thought guns were illegal in Mexico." He chuckled and said, "So you stayed in town last night?" As the conversation progressed, it became clear that guns are as common in Mexico as tamales at Christmas. Everyone he knows, including himself, own at least one gun. And, it matters not whether it's a semi-auto or fully automatic, they're all illegal, so why stop with semi-autos? Though clearly illegal in the states in most instances, a lot of Mexicans have more firepower in terms of military weapons than we can only dream of owning here.
As time went on, parties in the city at middle class Mexican homes become a way of life. Most Mexican managers in the plant knew I was a gun wonk. As it turns out, they couldn't wait to invite me over to their place on a Friday night to show me their collection. Semi-autos, some very high-end Sigs and other European handguns were not uncommon along with piles of old revolvers. I thought I had seen everything in the states, but in Mexico it's not uncommon for people to own full-auto military rifles. Everything from an M16, UZI machine pistols and the most popular, select-fire AK47 military rifles. These are not the so-called "assault weapons" you can buy at the local gun shop in the U.S., but full select-fire military-issue rifles. Now, I know you want to know and are dying to ask; Did I see any U.S. military-issue weapons stolen from the U.S. military? Not a single one was marked with U.S. military markings. Everything was marked with additional foreign markings on the receiver, including M16 rifles, or they had nothing at all. I saw firearms manufactured in Europe, China, Russia and South America along with U.S. manufactured weapons. I saw rifles that looked familiar with no place of manufacture, no serial number or manufacturer's logo. The information was not removed, it was never there to begin with. I can only assume they came from illegal arms manufacturers in India or Pakistan that produce copies of weapons. It was obvious that none of these firearms came from a U.S. gun shop in Tucson or San Diego. You couldn't buy them from a gun shop in the states if you tried.
