What Discmania has to say about the new P1:
 
P1 is back and better than ever before. We went back to the drawing board to create a new and unique take on everyone's favorite straight-flying putter. The slightly convex, rounded bottom provides a smooth and natural feel in hand that is suitable for players of all skill levels.As a slightly shallower cousin to the P2, this putter fits well with just about any type of grip style and is a tool you can count on for absolute precision both on the tee pad and on the green. Find your favorite flight with the P1!
 
Good for: Putting, Control backhand and forehand drives, upshots, scramble shots
