Hi John, The Reverse Striker is a mechanical trigger system rather than a traditional recoil-actuated trigger system. With the Reverse Striker, after one barrel has been fired the trigger shifts itself into position to fire the second barrel when the trigger is pulled for the second shot. It will not fire both barrels simultaneously. Only one barrel will be fired with each pull of the trigger.
The thumb-operated “safety” allows you to choose the firing order of the barrels. Barrel selection can be made only when the “safety” is in the on safe position. Sliding the barrel selector to the left reveals an “O” that indicates the top barrel (over) will fire first. Sliding the barrel selector to the right reveals a “U” that indicates the bottom barrel (under) will fire first.
It has a 60/40 Point of Impact.
Stay safe & have a great day!

Hi John and welcome. This model uses Browning’s “Reverse Striker” mechanical trigger. Yes, the non-automatic safety (r.) slides left-to-right for barrel selection. This model also has a 60/40 point of impact. Cheers, stay safe and enjoy!
