I carry the 96D in an SSIII holster, although I agree with Kermit that you should use what works for you. The D model has a lighter mainspring than the DA/SA version of the same gun, so the DA pull is lighter. (Some people will tell you to switch out mainsprings, but that would be a no no for me.) The trigger pull also is smoother. When I originally got to pick between the D, F and G (decock only) versions, I decided that I liked the first shot on the D much better than the first shot on the F/G version, and the first shot is the most important. (Some people who chose the F models picked them for the subsequent shots, rather than the first.) I also liked the fact that the D model has no mechanical safety or decocker, although a friend who chose the F model was saved when he flicked his safety on during a wrestling match, and I wouldn't have had that option. I also don't like the transition from DA to SA on the F/G models. 40 rounds of our qualification is done with 2 shot strings, and that really penalizes people who have to transition.
I would suggest that you handle both, and if possible, shoot both before deciding.
