1. My aging right hand is not what it once was. A revolving pistol does not depend upon a firm grip and a rigid wrist in order to cycle the action for the next shot. I am, actually, sufficiently ambidextrous to shoot with my healthier left hand*, but, then, if I have to run the slide, it would be that gimpier right hand grasping the slide. Notably, however, this does not mean that I cannot use an auto-loading pistol reliably, right-handed, but I am concerned that some of my auto pistols may not be best choices to trust in life-or-death circumstances.
2. I am able to get a really firm grip, on a Ruger SP101, with the factory grip, or an S&W K- or L-Frame, with compact grips installed. This is especially important if the weapon is being held in my aging right hand, and would become doubly important if a struggle happens at contact distance. A gunfight is a fight that happens to involve a gun. 33+ years of big-city police patrol experience taught me that things can happen really quickly, at amazingly close range. Now retired, as a private citizen, I cannot preemptively have my gun in-hand, in as many situations.
3. The Ruger GP100, as seen in my avatar image, has been what I shoot consistently best, on good days and bad days. I have owned that first GP100, in my avatar image, since some time in the very early Nineties. Some other medium and medium-large revolvers perform about as well, with suitable grips installed. Compact grips, on those same weapons, degrade accuracy somewhat, but make concealment easier, so, are acceptable.
Sometimes, for one reason or another, I will continue to carry suitable auto-pistols, but, my normal daily default “primary” handgun is a revolver. Sometimes, the revolver is what I carry for a right-hand draw, while an auto is positioned to be drawn and used by my healthier left hand.
Notably, “tradition” and being “old” have nothing to do with my preference for revolvers. As a kid, I was a history buff, and a fan of the 1911. When I was able to buy a handgun, at age 21, in late 1982 or early 1983, it was a 1911. Today, if I am toting an auto, it could be a 1911, or a Glock. I carried both during my LE career, as duty pistols. As a cadet and rookie, however, I was required to use revolvers, and I learned to like them, too. Tools for the task; choose wisely.
*I was born left-handed, but right-armed. I write lefty, but throw righty. During my police academy days, 1983-1984, drawing the then-mandated S&W L-Frame, from the then-mandated low-slung duty rig, was not unlike throwing. Pulling the DA trigger seemed to work about equal, righty or lefty. So, I developed the habit of carrying on my right side, which hard-wired my brain to reach for my right hip, during an emergency.
