Now I've gone through my share of Payday 2 achievements. However,there are still a few achievements which have got me stumped. In this case, it's the "Oh, That’s How You Do It". Essentially, you have to:
Fire the Vulcan Minigun for 25 seconds without reloading or letting go
of the trigger.
I have tried this several times. With a full magazine, when I just hold down the mouse button, it only fires for about 20 seconds thereabouts. In addition, there are no mods that can lower its rate of fire or increase its magazine capacity.
Is this achievement a troll? I really do not want to waste my time on it if it was.
Note: I play on the PC not the console versions.

You have to use the Enforcer skill Bullet Storm (Ace).
It allows you to fire without depleting your ammunition for 15 seconds directly after deploying an ammo bag.
