Glock Trigger Strange Thing Happening

[CTGunner]

I picked up a used Glock 23 and the trigger feels considerably heavier than my other Glocks. I'm assuming a heavier spring was installed.

When I pull the trigger on the unloaded gun I know the trigger should stay completely back. At least on my other glock it does, it sort of locks back.

On this gun the trigger locks back and then moves forward a bit as if it's under spring tension. It doesn't reset though, it just moves forward and remains under a small amount of spring tension. I can move it back and forth slightly (considerably more than any other glock trigger though).

Any idea what is causing this? Some kind of trigger modification?

I did put 100 rounds through it with no issues other than a very heavy trigger pull.

A New York trigger maybe?

What you're describing SOUNDS like a "NY trigger"; have you stripped this pistol down at all? The NY trigger mod replaces the tiny coil spring in the reset mechanism with a molded green or orange plastic Y-shaped spring, which you should be able to see if you take the slide off.

Took it apart. Yep that's what it is. The NY trigger. Thanks for the help.
