Clearly no care was given when the game was made to these things, so why would they fix it now? I could go at this all day and get nowhere. If anything it might slightly boost accuracy since you're not squeezing the trigger as hard, causing your muscles to tense less and the firearm would be less likely to move. What about aiming and aiming time, the fact that time still has to pass whiile the shot is fired, the fact that it doesn't take less time to pull a hair trigger than a regular one, just less pressure? It's like these guys had no clue how a trigger works. The 5% chance not to use an action? That's silly. what about when you reload? That 'removes' it from the weapon. Removing it 'breaks' it and it's gone for good. But you can't take the same mag extension off one M-16 and attach it to another one.

Yes, some fit multiple weapons, but you can't jam an M-16 extended mag on a 9mm pistol.

that's not how mags work, and they're usually weapon specific. That fits any weapon, but can't be removed. Why can't I replace the original trigger group, remove that 'hair' trigger and put it in another, identical, gun? No reason other than to force you to scavenge more junk from the battlefield. It's absolutely ridiculous to think that you can install these mods into a weapon, but can absolutely *NOT* take them out and use them elsewhere. I'm not sure if there is one but it should be built into the game.
