If you watch any cop shows or movies, you might forget — as you watch the good guys storming a building with their Glock 19s at the ready — what the purpose is of having a handgun.
As Chuck Taylor used to say (maybe he still does), a handgun is a reactive defensive weapon.
That means your handgun is a weapon you engage in reaction to a situation you did not or could not foresee. You do not storm a building with a handgun.
It also means that your handgun is for defending yourself, not for dealing offensively with situations.
If you’re going into a situation where you know there is a high possibility of armed conflict, take a carbine or a shotgun.
