I agree... Going into a gunfight was bad wording.
I had a good feeling that you didn't really mean it that way. You sound like a reasonable fellow.
I tend to see that as gentlemen who've chosen to arm themselves carry their weapons and accessories over a couple of decades, the extra stuff tends to start dropping off of their EDC. I know a kid who started carrying a Glock 23 with a laser/light lan as soon as he got his LTCH. He also carried two extra magazines of hollowpoints, a mini-mag flashlight, two folding knives 1 3", 1 5", a leatherman multi-tool, and pepper mace. This was besides the stuff we regularaly carry (wallet, keys, phone, etc...) His father and I used to laugh when he walked into the house and disarmed on the table in their living room for Sunday Football; saying, "What no handcuffs? Rifle? Gotta flashbang in there?" (all in good fun)
His father happened to carry a NAA Guardian in .380 IWB at 4 o'clock with a 4 inch Buck knife on his left side at a forward kant. Only. He used to tell him that, "That is simply too much stuff." And, "One day you're going to realize that you're never going to need all that." As the next few years progressed, things started dropping off. The third magazine fell by the wayside pretty quickly. After taking a few martial arts classes at college, he decided the pepper mace was a bad idea if you were going to get into a grappel anyway. He traded both bulky folding knives and the Leatherman in for a small lightweight Boker Magnum and got an S2 Juice multitool to drop in his pocket. He traded in his mini-mag for a Stylus Pro, and ended up trading in his Glock 23 for a stock .45ACP Glock 36SF. He still carries an extra magazine in his pocket (it's all but destroyed his cell phone), but he's down to a smaller firearm, 1 utility knife with multi-tool, a small flashlight, and an extra mag (about 1/3 of the weight as before).
Its just something you get more comfortable with over time. You realize that your brain and your training are really the best assets you have, and that you can "make it work" with just about any tool that's put in your hands. Then you pick a tool that works well for you and train the Dickens out of it. Everything else is just gravy. And when you get a bit older, you'll realize how many people will be telling you to lay off the gravy
