The current class of recruits is now required to purchase and train with either the Glock 17 or 19, according to the Sun-Times.
Supt. Jody Weis made an argument for a uniform weapon in March, speaking at the Union League club.
Current sworn members will not be affected by any of the changes, and they will still be allowed to choose any gun they want from the approved manufacturers.
According to the article the officers primary weapon will be the Glock during their 18 month probation but it is unknown what their options will be after probation.
