(Can only speak for the H&K and a Kimber.)
I really liked the trigger of my H&K USP Tactical .45, whether DA or SA. My wife’s H&K USP 9mm Compact’s trigger is fine also; not as good as the Tactical, but very acceptable.
However, twice, while using my Tactical for IDPA matches, I failed to allow the trigger enough forward travel to reset, and found myself pulling for a couple of seconds before I realized why it wouldn’t shoot. My fault.
Then I bought a Kimber SST-II, and I definitely like its trigger better than the Tactical. It is not so much the actual trigger pull, as the Tactical is fine in SA, but the big difference is reset travel. The Kimber resets in almost no distance compared to the Tactical. Just the nature of the beasts.
My wife shot my Kimber several weeks ago, and she just loved it. She said the added weight made it easier to hold on target, and she simple when nuts over the trigger. Her targets were proof.
For the H&K's: Neither the .45 Tactical nor the 9mm Compact have ever malfunctioned, no break-in was ever required, and they both digest any ammo I have tried. Also, both are 'very' accurate - my Tactical is as accurate as my Kimber, and the 9mm Compact, with 3-1/2 barrel is just great.
