Welcome to the Glock.pro forums!I recently installed a 3.5# Ghost connector. It took 15 minutes to install and costs about $30 . I also bought a KKM barrel from Glockmeister for $165...worth every penny.

Excellent!the pre travel remains the same, it just stops the overtravel. you still have to leave a little overtravel when you fit it. having the trigger stop right at the break in any combat weapon is a bad idea.
the overtravel bar stops the trigger bar from moving all the way back after the break.
if you don't over file it a little bit, after a couple thousand rounds when the trigger bar and connector wear against eachother, the gun won't fire. at that point, the trigger bar needs to move back just a little more to release the striker. it happens to people, and they think there's something wrong with the connector lol
