A word to the wise.. Changing the trigger spring and firing pin safety spring shouldn't cause any problem but I would reconsider the replacement of the firing pin spring if it's in a carry gun. You WILL have a problem sooner or later with a bit of a hard primer and have a failure to fire. I went through over 600 rounds of WWB without any issues in my 17 with the setup you are using and then had 2 FTFs out of two magazines. Both rounds fired when reloaded into the mag so I'm sure it was just hard primers.You'll need different springs as well. Just putting the connector in will not drop it to a 3.5 pound trigger pull. At least it didn't for me until I changed the springs out.
I just recently I put in the Ghost 3.5 lb. Rocket trigger kit. It's a piece of cake as long as you know how a trigger works. There is some filing and polishing to be done to get the gritty feel out of it and to get the trigger pull to exactly where I thought it felt good. You also have to replace your firing pin spring, safety spring, and trigger spring.
You can find the kits on Glock | Buy pistol parts, glock pistols, pistol magazines, and more but if you really don't know how to get to your trigger and you're not comfortable doing it yourself, you should look into having someone do it for you. I will say that I had a few compliments that mine feels 10 times better than what GlockDoc has done and for about half the cost.
If you deliberately modify your gun to a lighter trigger pull, and are involved in a defensive shooting, what might the jury think?
It's easy to say "it won't matter if it's self defense", but is that a chance you want to take?

Not someone's internet opinion, just sharing what I've experienced.

You dont NEED to polish anything. Change the connector and springs and its good. Never had a problem, thats the first thing I do to my Glocks.
