I don't think that "gadgetry" is the right word to describe a valuable addition to a firearm. Valuable, you might ask?
Sure, it is. Let me explain...........
If you buy a plain-jane .45 1911A1, and desire to use it for duty and/or daily carry, you might leave it like it is. Or, you might take it to a good pistolsmith to have Bo-Mar sights, or maybe Trijicon sights mounted. Of course, the beavertail, ckeckered mainspring housing, lowered and scalloped port, full length guide rod, hard-fitted match barrel of your choice, and trigger job to about 4.0 lb.
Is that gadgetry? I don't think so.
You might buy a rifle, and want it to shoot its best. So, here comes the custom barrel of choice, along with blueprinting the action, lapping the lugs, mounting a light stock, and depending on the caliber the scope of your choice. And, not a cheap scope either. Perhaps a Nikon, maybe a Leupold, Schmidt & Bender, Kahles, Swarovski, you name it.
Is that gadgetry? Doubt it.
So, let's say that I buy a shotgun.
I'm not worried about looks here, so I will not have a stock and forend blank hand fashioned from Circassian walnut, thank you very much.
I am aware that length of pull is important, of course. Too long, or too short will allow the shotgun to kick the poo-poo out of you--like my shotgun did when I fired a 3-inch Magnum slug through it with the factory stock mounted. Since I have very long arms, I deduced that the length of pull was too short.
Since I did not have access to a gunsmith with a try-stock, I selected the Hogue Comp-Stock. Nope--it's not pretty. Nope--it's not designed for a trap gun. It would have a lot of the PC shotgunners on Sundays turn their heads. But you know what?
I don't care one bit.
You see, I use that very ugly (to some people) Winchester Defender for one reason, and one reason only. That is, to place in a patrol car, where I might have to fire it in defense of my life, or someone else's life.
And, so, not having the money right now or the time to send off to Vang-Comp, I chose that CompStock.
Guess what?
I can now fire that shotgun with buck and slug mixed as fast as I can cycle the action--which, with the Winchester recoil-assist, is pretty durned fast.
At 50 yards, I can keep 8 3-inch 12 gauge 1 1/4 ounce slugs inside a 4 inch circle, rapid fire. The sights don't even move from the circle I'm aiming into.
Yep, my gadget works. Sorry if you don't like it.
Hey, Oleg---buy the doggoned Comp Stock.
