All codes above refer to the same curve family — just named differently by each manufacturer.
The P40 shares the same blade shape as the P88 family — same mid curve, closed face, and deep pocket. Introduced under the MacKinnon name on CCM sticks, it is functionally identical to the P88 used across Bauer, Warrior, True, and Sherwood. If your brand calls it P88, W88, or T88, the CCM P40 is the same curve.
Same fit as the P88 — stickhandlers and playmakers who want a deep pocket and closed face for puck control and low wrist shots.
