The use of the NY1 on Gen4, and now, thanks to F's excellent report, apparently the Gen5 provides a mushier pull than NY1s with previous generation Glocks.
On Gen 3 Glocks, I found that a NY2 actually provided a more revolver-like pull than a NY1, but required a steeper learning curve and considerable time and muscle-memory building to take advantage of. I tried it for a season on my Gen3 G21, and while I was actually somewhat pleased with it, I fairly quickly removed it at the end of that season, as I found my shooting results quickly trailed downward after 20-30 rounds due my trigger finger tiring with it.
Most of my Glocks now just use the OEM coil trigger return spring.
Best, Jon
