Different but better
The Glock trigger is made up of three main components: The trigger bar (which has the trigger shoe on the front end and a
nose at the rear), the connector that intercepts the rearward travel of the nose of the trigger bar, and the striker (AKA firing pin) that is released when the connector forces the nose of the trigger bar down and out of the way. (For more information, see How A Glock Works.)
The feel of the typical Glock trigger includes 1) a short section of take-up movement that releases both the trigger safety and the firing pin safety plunger, 2) a
wall of resistance when the nose of the trigger bar contacts the ramp on the connector, and the final travel which causes the trigger bar to move back (pushing the striker and compressing the striker spring) and then down out of the way to allow the striker to move forward to hit the primer of the round in the chamber, if any.
Like everyone else, I started with the stock connector, which I eventually polished to smooth things out. I was happy with it but continued looking for more. I tried a minus connector (AKA the 4.5 connector) and found it mushy. Then I discovered the dot connector (AKA the 5.0 connector) and thought I’d found perfection. The only problem is that I shot better with the minus connector (with the mushy trigger feel that I didn’t like) than I did with the dot connector with its nice
wall and crisp, clean break. For months I tried to train up with the dot connector to equal my performance with the minus connector but never got there.
Then I tried a Ghost Edge 3.5 connector (stock springs throughout in each of these setups). To my surprise, it eliminated the
wall to which I’d become so wedded. Without the
wall, the trigger pull felt smooth and natural from beginning to end. Comparing the Glock 4.5 connector to the Ghost Edge 3.5 connector, the 4.5 still has a defined
wall with (to me) a somewhat mushy feel afterward. The Edge 3.5 has minimal take-up with a very subtle
wall — AKA increase in trigger pull after the slack is removed from the trigger — before beginning the final section of consistently gradual movement rearward leading to the release of the striker.
This all has to do with the geometry of the Edge 3.5 connector, and how it differs from the geometry of other Glock connectors. If you compare the Edge 3.5 to the 3.5 Standard (which is similar to stock Glock connectors in terms of overall geometry), you will notice two main differences. First, the ramp (which guides the nose of the trigger bar down to release the striker) is offset toward the front of the gun, which shortens the take-up normally felt in a Glock trigger. Second, over-travel is reduced due to additional metal in front of the trigger reset hook to stop the rearward travel of the trigger bar after the release of the striker.
Interestingly, the Edge is not the most aggressive drop-in trigger (meaning you do not need to do any fitting to get it to work) that Ghost offers for the Glock. That distinction belongs to the Angel 3.0, which I have yet to try.
For those ready, willing, and able to do a little gunsmithing as they search for the perfect trigger response, Ghost sells a wide variety of trigger connectors. Some like the Edge are drop-ins that require only disassembly and reassembly of the gun, while others require filing, allowing you to fine-tune your action.
Not every parameter can be addressed by changing the connector, so Ghost also sells various springs and spring kits that allow additional customization.
I have shot so many rounds with the
wall that I still over-stage sometimes with the Ghost Edge, but I can train that out. In the meantime, I’m shooting much better. I don’t care if the pull is heavier or lighter. I don’t care if the pull is longer or shorter. I’m just happy to have traded my
glass rod break for a gliding trigger action. Also, by eliminating the
wall and the break, I’ve eliminated slamming the trigger to the rear and upsetting my sight picture, which no doubt plays a part in the increase in accuracy.
