Tactical means it is black and is used by "Operators", this definition fits anything termed "Tactical". Tactical pocket knives, tactical clothes, tactical boots, tactical wheelbarrow, tactical sunglasses, etc. and so forth. You are throwing a pretty loose and wide verbal rope when using the word tactical the way folks tend to use it these days. The term "Operator" needs to go in file 13 as well.
As far as paddle holsters go, and in an effort to remain on task, I have found that a good paddle is quite comfortable as a long term carry option. As has been pointed out, it can be uncomfortable for folks with spare tires around their middles. It is not as easily concealed as an IWB (Inside the Waist Band) holster. I have found the IWB to be the most easily concealed carry method for a full or medium sized handgun, but I do have certain pants I use for the IWB so I have a bit more room. OWB (Outside the Waist Band) holsters are comfy and pretty easily concealed. Simply Rugged makes the Sourdough, which I like quite a bit. Don Hume (out of business) used to make a pancake with thumb break and a steel reinforced open front that was just a real slick piece of work. Super comfortable, and fast. It was also easy to draw from a seated position with that rig. I do not believe anyone currently manufactures a copy. Too bad.
