An individual clearly cannot train for all possible scenarios he/she might reasonably expect to encounter. So, the question is:
- How do YOU decide which of the many possible scenarios are the ones you will train for?
- What goes into your decision to formulate the possible scenarios?
- From those possible scenarios, how do you decide which is most likely?
- Having decided which is most likely, how to you decide what training is needed and how to get it?
Hmm ..
I can't help but think many here are overthinking things a tad. I would hope that most here who've made the choice to carry a handgun for defensive purposes had already thought through the possible scenarios they might encounter, i.e., walking into a convenience store robbery, coming home to find your home was broken into, hearing a bump in the night and getting out of bed to investigate, walking away from a restaurant or theater with the wife when accosted by a rough-looking individual, shopping in the local mall on a mellow Saturday afternoon and hearing gunshots ...
There's so many possible scenarios that exist today with regard to incidents of public violence that if one stops to try and figure out which is most likely, one might go into brain-lock because the reality is --- today, anything can happen. If you're carrying a pistol while riding your bicycle down a city bike path and some terrorist comes up behind you in a rental truck mowing down all the cyclists like bowling pins, how do you defend against that?
Personally, I cannot decide what particular scenario might be the most likely that I'd encounter ... so I train on the fundamentals, continually working to be a better marksman while practicing drawing from concealment and shooting on the move. Competition helps get the adrenaline up and while it cannot simulate an actual gunfight, certainly in increases one's skill levels. I'm also fortunate to be the beneficiary of some awesome training courtesy of Uncle Sam and a few state, county and local governments ...
I don't typically stay out in public after midnight; I avoid public drinking establishments, I don't frequent shopping malls and I watch my movies after they come out in Blu-Ray ... I don't frequent bad parts of the city, nor do I socialize in public. I do go to restaurants, but we usually eat early dinners. The only time I ever feel really exposed is while hiking in the wilderness, fishing or hunting in remote areas or on long road trips, but there's a lot of ways to mitigate risk while participating in those activities.
I guess my answer is: I don't train for specific scenarios. I think about specific scenarios, and consider possible responses ... I train to shoot accurately, quickly and seek cover. Most of all, I practice avoidance.
Finally, though -- I totally believe in acquiring as much worthwhile training as one can afford both monetarily and time-wise. A recognized defensive handgun course taught by one of the masters is not only terrific fun, it'll usually turn you into a training junkie. But it's not just the tools -- courses taught by guys such as Massad Ayoob and Marty Hayes that lay the legal groundwork for you on defensive uses of firearms and teach you how to deal with the aftermath of a defensive use of firearms are, to me, just as valuable as that fun weekend carbine course ...
