this 'tactic' is rather changing the way you think during a heist its also usable on other games (ill let you decide in what games this tactic has little eficiency)
its mostly about seperating your loadout
one weapon for all-round purposes (long range close range and medium range) an assault rifle is advised but carbines and certain sniper rifles also seem to prove worthy with other heavy's
and one very powerfull weapon weapon for hunting down any type of prey

i call the weapons suitable for more situations the seekers
and the weapons for hunting i call predators

lets take a look at the weapons shall we?

ill show some of the seekers i use oftenly




seekers are weapons that can be used over long ranges they let you take out cloakers and tasers and snipers are easy pickings for seekers.

they should also prove valuable in combat (i usualy stay behind a corner and return fire when the cops ceased their shooting phase) however they're not so usefull on dozers (if you mod the clarion like i did it can make short work of dozers.)

the most important statistics of seekers are stability,acuracy and ammo capacity.

ill show you my predators of choice




these weapons are used to make short work of many enemies they are ment for tracking down and eliminating any type of enemy capable of causing serious trouble for the crew
the saiga you saw deals 60 damage per shot wich is pathetic for a shotgun but it can make short work of cloakers,responders,tasers (if you shoot them on time),maximum force responders and even bulldozers.
you oftenly use them when you heard a special unit and the amount of responders (or normal cops i have to say it for those who dont know what a responder is) is under control,this doesnt mean you dont need to be carefull!
the lmg is usable over longer ranges on large groups of weaker enemies.

the most important statistics for predators are damage,clip size,fire rate and stability. (not realy a must but is usefull for many predators)

here are my secondary seekers





if you're keeping a primary predator you must have something to fend of the snipers and combat situations,these call for a more nuanced weapon with solid acuracy high stability and a pack of ammo smg's are ideal for this,if you have my skill build you'll find pistols less apealing and mini shotguns are not advised because of their low acuracy,but with the right skills and mods you'll find many pistols very satisfying.

ill show you my secondary predators




the bronco posted here has a normal acuracy and is harder to use over long ranges in the hands of a well invested mastermind this pistol does 100 damage and has an attractive fire rate.

mostly shotguns as you've noticed the one that can make a kill the fastest is the judge of course with a high fire rate and a devastating amount of damage to go with that its safe to say that this weapon can take care of dozers and almost any other enemy with a single clip.

the worst one is the street sweeper i dont like it very much because of its tiny baby punch but with a he round its a different story then it can quickly take care of many enemies.

the locomotive is without doubt one of the most popular weapons and usable against many classes.

bonus tier

you keep them as a weapon but you use them for rather specific purposes these tools are used for cracking blasting and opening.

the blooper,thumper etc is a rather flumsy weapon but can take care of a group of weaker enemies or just a group of weaker enemies staying with a boxbeast like the bulldozers,it is extremely useful against dozers because of the high damage but is a curse to use if you're low on cash and there's civilians around (bain loses his mind) but its very reliable.

being a boon on day3 of firestarter the saw can be used to open almost anything up and can be used to make short work of a dozer.....if you manage to get close enough that is.

an uncommon sight the sentry turret but extremely usefull for holding your ground on certain missions sentries are not very strong and barely hit anything if you dont upgrade them.

c4 is usefull on many ocasions from skull cracking to door blasting if you have a few left and you need to use the drill for that last part anyway you should place them in random places they can be a real lifesaver for predators example:
i once was hunting down this cloaker and our technician placed trip mines everywhere i whot that cloaker before but her got away suddenly he shows up out of nothing and charged at me i first shot at the cloaker and then triggered the trip mine myself wich killed the cloaker (so without that random trip mine i probaply ended up in costudy because i strayed away quite far from the rest of the crew.

bulletstorm is a usefull skill that lets you pepper massive groups with any weapons it is especialy usefull when you got cornered by a bulldozer it doesnt matter if you're using your seeker or hunter if you can deploy your ammo bag on time you'll survive.

and that ended my guide about my tactic know that im not trying to dictate what your loadout looks like im kindly suggesting some tactics you may want to consider if you wear heavy armor like me.
