It's discussions like this one which serve as a reminder of how much I miss the days when a handgunner considered it normal to be able to competently handle, manipulate and shoot a DA revolver, a SA revolver and a SA pistol (aka:1911 or Ruger Standard).
The advent of the variable DAO-ish plastic pistols has, in a way, lowered the bar for acquiring a good foundation handgunning skillset.
For example, As a long time 1911, SA & DA revolver shooter, who was carrying a service revolver, I was less than enthusiastic when I had to turn in my revolver for a then-new S&W 5903 (alloy framed, traditional double action, meaning DA & SA function). As a long time 1911 and DA revolver shooter, though, it was a pretty easy acclimatization to using DA for the initial shot, and SA for subsequent shots (unless decocked back into DA). Just a new way to use existing trigger control skills and experience.
Fast forward about 27 years later, 26 of those years having served as a LE firearms instructor, and my retirement CCW handguns are comprised of a smattering of Glocks, M&P's, SW99's, S&W 3rd gen pistols (TDA), 1911's ... and DA/DAO revolvers and a couple of Ruger LCP's. They each feel familiar and comfortable in my hands, and they've all been used for training, quals, casual drills, etc.
My "favorite" triggers will remain both a 1911 and DA revolvers (tied for first, so to speak), followed by the TDA (DA/SA, if you'd rather, which includes a couple of my SW99's), followed by the "striker-fired" DAO-ish.
One thing that seems to have remained consistent over the years that I've served as a firearms instructor is that handgunners who are well versed and skilled with DA revolvers, seem to be able to shoot other handguns, of other designs, more easily than folks who learned their handgun skills on just plastic pistols.
