Is your GP100 new? If so, it might break in after a few hundred rounds or so and smooth out, as mine did. Also, dry-firing with snap-caps while wathcing TV helped mine. (I know, you know, but just triple check that its unloaded).I agree with you that the triggers on most modern DA revolvers need work. If you can't find anyone locally, there are a lot of smiths that do great work that you could send it out to. Just a suggestion.
