Cost to change over was a major hurdle.
Not the cost of the gun as much as the cost to re-train all the members.
When my old department switched over from Ruger Service Sixes to Glocks it was a 3 day training block for almost 2000 members, so the transition took a couple years.
There was also major resistance within some on the City Common Council and Mayor's office as to the idea of cops having "Semiautomatic" weapons. They control the purse strings.
