FWIW, I changed the connector in my G48 and cannot say I can feel a difference. According to my scale, there may be a reduction of once ounce.
The stock trigger is better than my other Glocks.
I have not done it to a Glock, but I did cut 4 coils off the striker spring of my FNS and it did reduce the trigger weight.
On a Glock, i would be afraid of a light striker and poor ignition.
