Yes, in fact Glock had to design a retrofit trigger spring and connector in order to meet NYPD's contract requirements. I have a bunch of extra connectors and springs for Glock pistols and have tried it out in the NY configuration. It's awful. They basically want their semi-autos to function as double action revolvers with magazines. Combine this with the fact that the huge majority of cops are not "gun people" and only shoot the minimum required for qualification, it's little wonder they have poor field results.
