do you play tennis or baseball? Just mastering the various clubs is enough hassle, right? If you aim is to be good at gunfighting, why complicate things by having/carrying lots of different "feel" guns, especially with different manuals of operation. If you don't like to have to remember to manipulate a safety on a handgun, what do you do with a longarm, hmm? there aint any DA rifles or Glock shotguns. Stick with SA autos, so you don't forget and dont shoot yourself, either. Why deliberately handicap yourself by using a DASA for this and a revolver for that?
