as mine did, so it seems your work has you to be in places and under circumstances that, given a choice--you would chose not to.
such it was that i developed methods of carrying myself and accessories that served me perfectly for 4 decades.
i say 'perfectly' cause for all the attempts on me from many directions and degrees of ingenuity; none ever even had me cause to fire a shot.
i can say that they lacked surprise and the most fell apart before they really got started.
one has a primary and a secondary.
life comes at you fast and from many directions
one trains in a martial arts....havig a gun means not that it is always the answer--
or even the best answer. taking a knife away from a punk can be rather...disarming; and off putting for him and his friends to have happen.
one has multiple combinations of 'weapons' as the weather and manor of dress change.
as does where and when you may be somewhere.
and that your arrival may be different than your destination--you have back up plans...indeed-many of them
the what-if game is on going as long as you are awake--but it is in the back ground of your mind and only comes forward if there is something 'odd'
as to which guns you chose at any given moment from yours accumulation--thats based on your personal fit and fitness level.
never felt the need for a bigger gun; a Defender or p-239/40 sufices.
its is the presentation more so that counts.
how you train is the same in theory. if what you have been doing did not work, neither would you be for long.
