Xtrfy M42 (lower back) – Shape & Fit Overview
The Xtrfy M42 (lower back) is a wired ambidextrous gaming mouse weighing 59g with dimensions of 118 × 63 × 38mm. Its rear-mounted hump makes it particularly well-suited for claw and fingertip grip styles.
For hand sizing, the M42 (lower back) fits best for hands measuring 169–215mm in length and 74–90mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.
At 59g, the M42 (lower back) is classified as ultralight. Ultralight mice under 60g are a favorite for FPS players who prioritize fast flicks and reduced wrist fatigue during long sessions.
The PixArt PMW3389 sensor is a high-performance optical sensor delivering accurate, consistent tracking suitable for the most demanding competitive use. Maximum DPI is 16,000. Polling rate: 1000Hz.
