Realistic Pistol

I’m requesting from anyone that likes realistic SWEPs and can make them. I don’t know how to make an SWEP, so you would probably be on your own. What I mean is REALLY realistic. Such as: a LAM that you can attach and detach, a silencer, maybe an attachable scope, and pressing reload+E key would drop the clip currently in the pistol. Maybe even a menu to choose attachments to attach, like the COD attachment system, without limits.
