Astute fans know that many great figures of the MMA world are also great aficionados of firearms.

Just this month, the “gun lifestyle”-focused Recoil Magazine included a feature on a member of MMA’s first family: Heather Gracie.

Gracie remarked when asked how she found an interest in guns, “all of my uncles, my cousins, everyone is a shooter.”

She frequents gun ranges in Arizona and her hometown in Las Vegas, Nevada when not advancing her modeling and DJ career, and included some photography from the article on her Instagram account:

Another Las Vegas resident who famously enjoys spending time at a shooting ranges is former UFC Heavyweight Champion Frank Mir.

But unfortunately, Mir found the worlds collide in a less comfortable manner when he arrived in Brazil for his bout this weekend against Antonio Silva.

As reported by MMA Junkie today, Mir was stopped at the airport with a few rounds of ammunition in his luggage — causing a delay in his travel.

According to Mir, his 9mm cartridges weren’t noticed at airports in Las Vegas or Los Angeles. But Brazilian officials halted Mir upon arrival, held his passport, and contacted police.

Mir would call UFC President Dana White, and when police arrived, everything was quickly sorted out.

“The gentleman came over, and he had a smile on his face,” Mir said. “He handed me my passport and let me know that I could have the passport and he was going to keep the bullets, and to try not to make that mistake again.”

Mir says it was a simple matter of using his gym bag at the shooting range and not cleaning things out.

The heavyweight bout between Mir and Silva will headline UFC Fight Night Sunday in Porto Alegre, Brazil.
