I recently tried out the Glockmeister 6lb trigger spring with three different connectors. It didn't work out for me, but that may be the result of something else and not the fault of the trigger spring.
I installed the GM spring in my dad's Gen 1 G17. I found that the 6lb trigger spring did reduce the trigger pull weight, but it was negatively affecting the reset. During the reset, the trigger would not move forward all the way. It would only reset to the point where the trigger would break. I found this strange because many people praised the GM spring online and never wrote of something like that.
I'm not a glock expert, but I think it could be the striker spring that's causing this problem for me. Since the striker is supposed to catch the trigger bar and bring it back to firing position, I think it could be that the striker spring that is not strong enough to overpower the GM spring's increased strength. This G17 is 25 years old, and Grant recently posted about replacing springs in a Gen 2 G19 as preventative maintenance. With the exception of the recoil spring, all the springs are still the original in my G17. I guess it's possible that the striker spring has lost some strength over time, but again I'm not a glock expert. Maybe it'll work better for you with newer Glock.
I did measure some trigger pull weights with various connector and trigger spring combos. This is what I recorded for the stock connector:
5.5 Connector/Stock Spring: 6 lbs
5.5 Connector/GM Spring: 5.5lbs
I tried a new connector that I did end up liking more than stock and 3.5 connectors. Its the Ghost 4.5 Ranger. It's lighter than the stock 5.5, but does not add the increased mushiness and creep of the 3.5 connector. With 4.5 Ranger installed I got these trigger pull weights:
4.5 Ghost Ranger/ Stock Spring: 5.0 lbs
4.5 Ghost Ranger/ GM Spring: 4.5lbs
Because of the reset problems with the GM spring, I currently have the Ranger and stock trigger spring installed. If I could solve the reset problem, I would definitely go with the Ranger/GM setup.
Know your role, and shut your mouth.
