In light of the shootings that have plagued our country lately, has anyone been compelled to change their carry habits?...
Not really.
I've invested too many years having carried an off-duty (and now retirement) weapon that my habits and practices are pretty well ingrained. Having served as a LE firearms instructor and armorer for many of those years had more of an effect on my choices and practices, as it exposed me to a lot of training and data which seemingly doesn't often interest the average line cop. (I've always been considered a long time "gun nut" at my former agency, too.)
Sure, for some out-of-state road trips I may add an additional LEOSA weapon of a relatively larger size, basically meaning a compact or subcompact 9, .40 or .45, and even relatively "local" travels and "current events" may prompt me to replace a smaller gun with a slightly larger one at times, but I did that on my own time back when I was working, too.
FWIW, for road-trips that "larger" LEOSA weapon is mostly taken for the time spent in the car, against potential threats that may occur in and around vehicles. Mostly, that's meant that while I may be pocketing a 5-shot snub or LCP during the trip, I have something at hand while traveling in the car like a 4013TSW (9rd/.40); CS45 (6rd/.45); G27 (9rd/.40) or G26 (10rd/9).
Mostly, my everyday/night retirement weapons are either one of my 5-shot J-frame snubs (more than half a dozen), or one of my LCP's (pair of them).
I'm not nearly as concerned about
capacity as I am about being able to run whatever I'm carrying and get an initial1-4
fast, consistently accurate hits on my intended target. That's meant a lot of hours working as an instructor and running all of my different handguns through the same quals, drills and training sessions.
Sure, the greater capacity of modern service/duty type pistols do offer some advantages over pistols of "only" 5-8 rounds, but I've seen far too many instances where people seemed to put more emphasis on "capacity" than they did their innate skills and abilities.
If anything, if someone were to ask me what they ought to consider changing about their lawful CCW practices, I'd always recommend more attention to training and practice, versus just looking to carry a "bigger" gun or "more ammo capacity".
Hits matter. Misses are still misses, no matter how many of them you have the "capacity" to send downrange.
Most center-fire handguns that hold 5-8 rounds, before reloading is necessary, have the ability to put that many rounds accurately on the intended target, but only if the shooter does their part.
