Khan is one of the many bottom of the barrel Turkish made shotguns - almost, nearly looks like a shotgun. If you are lucky, you might get a "good" one that lasts a few thousand rounds.
I don't like trusting to luck to get value for my dollars. I am one of the many proponents of the "B" guns on this site, and used offers good value - Browning and Beretta guns last several lifetimes, unless used by very high volume competitive shooters (whose ammo cost far, far exceeds their firearm cost).
The suggested Trap combo is not insignificant money. Yup, it looks like a much higher value shotgun. What are the odds that it will work like it is supposed to?
Your money, your risk.
