I wouldn't replace the connector. The only time I have is because I have had a couple start flaking on me. This was when I was using a ny1 spring.

I *strongly* recommend against polishing anything in a Glock, save maybe for the firing pin safety. I've never seen polishing improve a Glock trigger pull. I have seen it cause reliability problems.
You can replace the trigger spring with a heavier one from Glockmeister, which will cut the total trigger pull down by about 0.75#. You can also replace the striker spring with a lighter one, which will reduce the second stage only by about the same amount, and will probably also give you some much-needed practice in clearing failure-to-fire malfunctions. You generally can't use both springs at the same time, as the trigger will not reset far enough to engage the trigger safety - not cool.
Finally, you can replace the factory connector with a Glock 'minus' connector or a Lone Wolf 3.5# connector. Either of these will lighten the entire trigger pull, but will also make the trigger release a little longer. I actually prefer this, so I use Glock 'minus' connectors in all my guns.

I will work on that next, then.
I will heed your warning re: polishing – this is my primary carry gun, and I don't want to leave anything up to chance.
I'm pretty happy with the stock Glock 5.5 trigger pull, and want my old 26 to get back there. If the new trigger spring and slide cleaning don't do the trick, I will try a minus connector.
This is a defensive gun, so it bears repeating... Take it to someone credentialed to do what needs to be done, or with demonstrated ability to do what needs to be done. Despite internet lore to the contrary, the guns are not legos and subtleties exist affecting parts variables and interaction that affect overall reliability.
Don't do the .25 trigger job. Don't replace the internals with non-OEM components. A lack of knowledge and stacking tolerances create paperweights. There's a high probability that you'll be back here with more troubleshooting.
If the gun has been completely cleaned, found to be GTG, and still has a trigger that you don't care for, you could obtain OEM components and swap them. Many times, just a trigger bar or connector swap will appreciably change the feel of a given combination.
I have fixed more guns "improved" by owners more than any other repair task. There's a reason for that.
First be sure the connector is properly seated and not even slightly bent. (this happen a lot when it is removed incorrectly: never pry it out) Next check the trigger draw bar make sure that this is not bent either. If you have shot the gun for sometime like this, it is possibly you have some microscopic grooves that are now rubbing/binding. Think of a dirty non-lubed gas as acting like sand paper against metal rubbing metal. It is also possible that the striker cups could be misaligned and rubbing inside the slide or even the firing pin sleeve cracked or broken. (Do not remove the sleeve unless you have the proper tools and training)
P.S. stay away from the so called 25 cent trigger job, or you'll get what you pay for.
Leave the connector. Replace all the springs. Clean. Lube. Should be good to go.
