I've always noticed that the reset on a Tac Sport is less tactile than, say, on a Shadow. You have only a single-sided trigger bar (as opposed to the CZ75/SP01 bowed/double) hence less reset-spring 'kickback' on it. Switching from the stock plastic to an aluminum trigger helped a slight bit, but I just let my finger out and trusted that it would reset where it did and it never failed. Didn't short-stroke unless I was trying to ride the reset, but I've recently stopped doing that as much with all my pistols.
