Well, you’re definitely correct about many PDs using revolvers before switching to Glocks. That goes back to the Miami shootout with the FBI; FBI agents were still using revolvers at the time, and they were significantly outgunned b/c one of the suspects was armed with a Ruger Mini-14 rifle. As a result, the FBI started looking for a better sidearm, and the initially settled on 10mm before adopting the .40S&W. Glock managed to bring a .40S&W pistol to market before Smith & Wesson did (!!!), and then charged below cost for PDs in order to convince them to adopt the then-new firearm.

And after finding an article about it, it looks like the NYPD did want to match the pull of their old double-action service revolvers. Which is nuts.
