Does everyone know their Glock has a trigger reset of aprox. .25". I can't hold my tape measure perfect but from what I can tell its aprox between .180 and .25"
For those who are not aware of a trigger reset, of course make sure your gun is unloaded. Dry fire leaving your finger in full trigger pull, rack the slide then let off the trigger until you hear, feel the click. That is trigger reset you don't have to go all the way out to the safety positions.
