Just watched this video after I received the link from a friend in France - the rifle has 3 triggers, one for each barrel and is offered in 458 Win and 470 NE. Unusual design - I'm not sure if there have been other three trigger drillings before - but Eric Mathelon is a genius. The guns will be very well made.

Waiting for the experts' opinions . . .

Good hunting, everyone! Youtube link from Chassons.com
