What also cracks me up is people talking about the weapon system that they are "running". I wanna ask them where they are running to and why they are running.
Hmmm... now that's one I use myself. But for me it means something very specific.
I can
shoot just about any firearm at least passably. But owning it, and being able to fire it, and understanding the maual of arms for it, is not quite the same thing as being able to
run that gun.
Running that gun requires dedicated, focused time (usually a fair bit of time), training with that gun until drawing/shoudlering it, pointing it, aiming it, firing it, reloading it, going to the support side with it, clearing common problems/malfunctions with it, and so forth can be done smoothly and (almost) un/non-consciously while I'm focusing on the problem/scenario at hand.
I shoot a 1911 during some seasons of competition. At other times I'll shoot my 629, or my xDM, or something else. I can pick either up and shoot them well. It takes ~500-1,000 rds. of re-education for me to really
run that gun* well.
(* -- I'll even go so far as to say that gun "system," or "platform" as using the weapon effectively requires having an unconscious familiarity with the holster, mags, mag carriers, speedloaders, and whatever other accessories are specific to that gun.)
I've got a small pile of firearms that I own/shoot. At any given time I'm only really "running" one or two of them at top competence.
