What it is, in one paragraph
The Pro-Mark Mike Portnoy 420X ActiveGrip (SKU TXMP420XW-AG) is Mike Portnoy's current signature drumstick, built by Pro-Mark, the drumstick brand under the D'Addario umbrella. American hickory, 16 1/4 inches long, .565 inch diameter, long taper, oval wood tip, finished with Pro-Mark's heat-activated ActiveGrip coating. Pro-Mark's own artist page quotes Portnoy directly: "My 420X sticks are the perfect medium between Metal and Prog, and have become my go-to for all the different bands I play with." It sits alongside his earlier 420 nylon-tip model, which Pro-Mark still sells, as one of two current Portnoy signature sticks.
Who Mike Portnoy is, briefly
Mike Portnoy co-founded Dream Theater in 1985, anchored the band through his 2010 departure, and returned in 2023.

Where it sits in the prog-metal stick lineup
| Pro-Mark Mike Portnoy 420X ActiveGrip | Pro-Mark Mike Portnoy 420 (original) | Pro-Mark Neil Peart PW747W | |
|---|---|---|---|
| Wood | American hickory | American hickory | Shira Kashi Japanese Oak |
| Length | 16 1/4" | 16 1/8" | 16 1/4" |
| Diameter | .565" | .531" | .551" |
| Taper | Long | Medium | Long |
| Tip | Oval wood | Oval nylon | Oval wood |
| Finish | ActiveGrip coating | Lacquer | Natural lacquer |
| Best for | Heavier hitting, sweaty-hand grip security | Brighter, more articulate attack at a lighter feel | Denser wood for hard-hitting multi-tier kits |
The 420X is the heaviest and largest-diameter of the three, the ActiveGrip coating is the differentiator no other stick here has. Portnoy's own original 420 trades size and grip tech for a brighter, lighter nylon-tip attack. Pro-Mark's Neil Peart PW747W, a fellow prog-genre signature stick from the same company, swaps hickory for denser Shira Kashi Japanese Oak instead of a grip coating. All three are Pro-Mark signature sticks built for technical, hard-hitting progressive drummers; the choice comes down to wood density versus grip technology.

What the stick is built for
- Heavier, harder-hitting playing. The 420X is measurably heavier and longer than Portnoy's original 420, a thicker profile built for harder-hitting technical playing.
- Sweat-resistant grip across a long set. The ActiveGrip coating gets tackier as your hands warm up, targeting the exact moment a set gets physically demanding.
- Sustained prog-metal technical vocabulary. The long taper and rebound balance suit fast, dense fill work and extended double-bass patterns rather than a single-hit power stroke.
- Not for players chasing a brighter, lighter nylon-tip attack. Portnoy's own original 420 or a standard 5A covers that lane better than the heavier 420X.
Verdict and the affiliate hook
If you want the stick Mike Portnoy plays now, the 420X ActiveGrip is it: Pro-Mark's own artist page names him directly and quotes him calling it "the perfect medium between Metal and Prog." Hickory, 16 1/4 inches, .565 inch diameter, long taper, oval wood tip, ActiveGrip coating. For a lighter, brighter-sounding alternative from the same artist, his original 420 nylon-tip model is still sold. For a denser-wood alternative from a fellow Pro-Mark prog signature artist, see the Neil Peart PW747W.

Why this one: Mike Portnoy's current signature stick, named on Pro-Mark's own artist roster: hickory, long taper, oval wood tip, and a heat-activated ActiveGrip coating built for the heavier playing he shifted into.
