Invector is a brand not a choke. Invector is a brand not a choke.
Invector was Brownings original choke tubes that came out in 1983. Invector Plus came along later for the back bored barrel shotguns. They are not interchangeable. Invector Plus= late model shotgun, Invector = earlier design shotgun. Both are still available for purchase.
The Invector, or "Standard Invector" system" was introduced in 1983. A few years later, the Invector-Plus chokes were introduced to fit the new back-bored shotgun barrels. These two choke systems will not interchange. If you have screw-in chokes in your shotgun barrel, the kind of system you have will be stamped on the barrel near the receiver. You must use the proper choke system for your shotgun.

Yes, as long as it has the right choke for slugs (cylinder or improved cylinder), the vents will make no difference to the slug, and will reduce recoil slightly.

I don't think there is an invector plus model. Invector Plus is the choke system Browning uses on newer shotguns.
Invector chokes are interchangeable choke tubes used in shotgun barrels to modify the spread of shot patterns. They allow shooters to adjust the constriction of the barrel, which influences how tightly or loosely the shot is dispersed over a distance. This adaptability makes Invector chokes popular among hunters and sport shooters, as they can optimize their shot for various shooting scenarios. The system includes different choke options, such as improved cylinder, modified, and full, catering to diverse shooting needs.

No, Invector chokes will not fit the Browning Medalist shotgun. The Medalist typically uses fixed chokes that are integral to the barrel, while Invector chokes are designed for Browning shotguns with removable choke systems. It's important to check the specific model and choke compatibility for your shotgun.
