pull and release trigger?

[olsmokey]

Reading an auction bill that has advertised two browning shotguns, BT has a release trigger. OK know what that is. Over and under has pull and release trigger. Are they talking about the same thing? Can a release trigger be changed back to a pull trigger? Dave

On the pull and release trigger it would be set up so that the first barrel would shoot normally by pulling the trigger and when released it would fire the second barrel. This would be strictly a gun for shooting trap doubles.
