In pistols, I carry a Glock 27 or a Kel-Tec .380. Although the triggers feel very different, the guns themselves are the same in that there is nothing to do BUT pull the trigger as is the case with many of the DAO types discussed. (Sounds a lot like a revolver, doesn't it?)

Anything can be learned and adapted to with training/practice, but I still prefer the "KISS" principle (Keep It Simple, Stupid).
