Correct. Per CGW
"What does the CGW disco do? The disconnector only eliminates the trigger pre-travel in SA. It cannot change the SA reset distance, nor can it change the double action position of the trigger...............The primary benefit of the disco is the instant the trigger resets in SA, the disco STOPS the trigger at the precise moment of SA trigger reset, eliminating the SA pre-travel "slop" in the trigger."
Sorry I ment to say the sa pretravel. I spent 4 hours and a wasted diso for no improvement. I've come to realize maybe there's something other than the wedge that needs to be trimmed.
Then you absolutely fit it wrong, when fit correctly it reduces the travel/SA takeup dramatically
