Mechanical triggers vs. inertia triggers
Good mechanical triggers are expensive. A set of Kreighoff triggers probably cost more than a 725 for the triggers alone. Inertia triggers work just fine. A 12 gauge gun will need to have the triggers worked on if you are shooting real light loads - like .410 loads through tubes. The modification is fairly simple on the Berettas.
