I honestly felt some of this before I fired a real weapon. I thought I could at least operate a gun, which in simple terms as putting ammo in and pulling triggers is learnable. But in the problem any one of these people will run into, is accuracy. In games, the sights are 100% accurate and you never have to do anything to fix them. In real life unless you a gunsmith with an accuracy fetish you cannot just have accurate sights, most of the time your gun will shot high or low so you have to compensate. The another main contention I ran into when I had my head so far up my ass I didn't need ear plugs was the fact that most people don't realise how fucking loud guns are. Also in games you get attached to weapons that in real life aren't considered effective. The last more substantial problem with this effect is guns aren't perfect like they are in the game. They weigh a lot, they jam a lot. And jamming doesn't get solved by reloading, you have to take a knee and sometimes strip the gun to get something unstuck. The other part along with this is the way magazines work, in games you get 30 round mags and when you reload with 15 rounds left it is full again next time. In real life you have to put each bullet in one by one and many people who have never fired a gun don't realise that if will hurt the hell out of your fingers the first hundred times you do it.
