Nickname
Colt 45’s – The Houston Colt .45s were the first Major League Baseball (MLB) team in Texas, and their nickname has a unique origin story.
Houston Colt 45’s Origin
The team was founded by Bob Smith, who owned several car dealerships in Houston. He wanted to name the team after his favorite gun - the Colt .45 revolver - but MLB rules prohibited naming teams after firearms at that time. So Smith decided to use "Colt" as an homage to his beloved revolver while also paying tribute to Texas' cowboy culture with "45’s."
Though they only played for 10 seasons before moving and becoming known as the Astros, it is clear why this nickname resonates so profoundly with sports fans: it pays homage not just to baseball history but also connects back directly to Texan heritage through its nod toward cowboys and gunslingers of days gone by. It is an excellent example of how one man’s passion for two things he loved – cars and firearms – could be combined into something memorable that still stands today more than 50 years later!

Houston Colt 45's History
The Houston Colt 45's history traces the origins of one of Major League Baseball’s original expansion teams, now known as the Houston Astros. Founded in 1962 by entrepreneur and oilman Roy Hofheinz, the team was created to bring major league baseball to Texas. The franchise played its inaugural game on April 10, 1962, against the Chicago Cubs at Colt Stadium, located near downtown Houston. The 1962 Houston Colt 45's marked the beginning of professional baseball in Houston, setting the foundation for decades of growth and success.
Although the team struggled during its early seasons, the Colt 45s quickly became competitive in MLB. In 1965, the 1962 Houston Colt 45's achieved a milestone by winning their first National League pennant behind star players like Joe Morgan and Rusty Staub. They faced Mickey Mantle’s New York Yankees in the World Series, falling short, but still making history as the youngest expansion franchise ever to reach a World Series at just three years old.
In 1966, after four seasons at Colt Stadium with its limited 32,000-seat capacity, ownership began construction on the Astrodome, the world’s first indoor domed stadium. Opening two years later with seating for over 50,000 fans, this move coincided with the team rebranding as the Houston Astros. The organization experienced further success in the 1980s under manager Bob Lillis, making back-to-back playoff appearances from 1980 to 1986 and winning five division titles during that span. The Astros quickly became a fan-favorite franchise, both for their on-field achievements and their connection to the Houston community.
