Hope I've made my question clear.
There's nothing magic about a trigger. They're simple levers only. If they reduce pull weight by having your finger further from the pivot pin, they increase the distance you have to pull before the sear releases. That's the tradeoff of changing triggers.
If you have excessive creep, reducing the overlap of the hammer notch and sear is the solution. Having a gunsmith do the work for you is recommended for keeping the gun safe and reliable.
That said, I reduced the hammer shelf on my MKIII and the sear ledge on my MKII. Both methods can work well, but they have pitfalls if you don't understand all of the subtle implications. I had to replace the first sear I modified after the "breakaway angle" (recommended by one forum gunsmith) degraded to lack reliable function. It probably would have been okay if I could have re-case-hardened the modified area. But instead I developed a different mod for the replacement sear to kill the creep.
Both pistols now have awesome creep-free triggers.
