Major League Baseball had previously mandated for the team to wear a modified jersey that doesn't include the pistol. The franchise was called the Colt .45s when it was born in 1962, with the uniforms featuring a smoking pistol.
In a statement released Friday, the team said: "Over the past few months, the club has been in discussion with Major League Baseball about whether to wear the authentic Colt .45s jersey. The original logo features the Colts name and a pistol. The alternative jersey would only have the Colts name on the front of the jersey. This week, MLB informed the Astros that the decision would be left to the ballclub.
"The Astros organization continues to value fan input, therefore the Astros have been reaching out to fans the past week to get their opinion on this issue.
"Our fans have expressed overwhelming passion and support for the Astros and our rich 50-year tradition. We plan to announce our decision tomorrow, Friday, March 9."
One of the cornerstones of the Astros' 50th anniversary campaign is "Flashback Fridays," when the club will wear some of the most recognizable and iconic uniforms in its history. The Astros are scheduled to wear the Colt .45s jerseys on April 10 against the Braves, and April 20 against the Dodgers.
