Recoil in firearms (especially handguns) is a "3 stage system". The 1st stage is just the bullet itself coming out of the gun, this will generate about 1/4 of felt recoil. The 2nd stage is when the slide/ bolt carrier reaches the end of its travel. That is a large burst of felt recoil that is significantly stronger on handguns. On rifles it depends. If the gun has a lockup system like an ak or an AR, it will be about the same or a bit stronger. On "pistol caliber carbines" the 2nd stage will be significantly stronger due to the use of a different gas system. The 3rd stage is when the bolt or slide goes back forward chambering the next round and pushes the gun forward a tiny bit. Bolt/lever/pump actions only have 1 stage of recoil due to the lack of a reciprocating mass. A good place to look for slow motion videos of guns being shot is ballistic high speed. If you have any in depth questions feel free to dm as well.
#How to make realistic recoil: a guide + some bonus gun gameplay suggestions

They already got realistic recoil what is this suggestion
Other gun suggestions: if the player is using a handgun with 1 hand and the grip button isn't over 50% the gun will stovepipe and jam.
Squibs: a 1 in 1m chance the gun will have a squib load that if not cleared with a blank or shoved out of the barrel will make the gun go boom
I've seen over 200 games do it wrong
This is how it works in real life
I’m pretty sure the devs know how recoil works considering they already added realistic recoil in the game 
This sounds like quite many annoyances
They are calculating caliber and weight. They should also calculate reciprocating mass. The recoil right now is as if all the guns were bolt action
@onyx dirge
They already added realistic recoil, as I said.
They don’t need to add on more 
He may have a point let him speak
I'm saying they did it wrong
Their math is wrong. When you shoot a gun, the bolt moves forward and back and that movement is like half of the felt recoil. This isn't represented in the current system.
Do you have a reference video or something similar?
Let me find one for you
For everyone reading this 😉
