I have a number of DA/SA pistols (Sig, SW 3rd generation, CZ, Beretta, HK) and by far the best DA/SA trigger are the SW 3rd generations. All of mine in 9mm (5906, 6906, and 3914) as well as the .45's (4516-1, 4566tsw) have a nice smooth DA trigger, short reset and a crisp-no creep SA pull. The Sigs are OK in DA but have a longer than desirable (for me) reset- although Sig does now offer the SRT (short reset trigger) which many people think is a big improvement. The HK (USP series) has the worst DA trigger by far- long, heavy, and severe stacking before breaking. I'm sure others will chime in with their preferences.
