I am of the belief that NYPD only authorized 9mm.
That aside, I have a 2001 September made k-9 that was indeed a NYPD Gun. I bought it from a friend of mine who HAD to sell it under NYPD orders.

Clearly a gun not used very often. That1/8" difference is all in your mind, like any other trigger, there is a pull until the bang and I would tell you theres no noticeable difference.
The reason the NYPD ordered them all sold was due to a higher than acceptable rate of "Accidental Discharges" 99% was due to poorly trained cops holstering and unholstering with the finger on the trigger....
