Compact 9mm comparison: MC9 Prime, GX4, CZ P-01, and Ruger RXM
Compare four sourced 9mm references by size class, capacity, barrel length, weight, and operating format.
All four references use 9mm Luger, but caliber is where the similarity ends.
Micro-compact is not one standard size
The MC9 Prime and Taurus GX4 belong to the broad micro-compact conversation, while their published size and capacity values differ. The CZ P-01 is a heavier metal-frame DA/SA compact, and the Ruger RXM is a modular striker-fired compact.
Compare format before small numeric differences
Operating system, control layout, grip geometry, magazine configuration, and optic mounting can create more meaningful differences than a fraction of an inch. Use the product comparison tool to keep the exact records side by side.
Current notice Taurus maintains a serial-number-specific GX4 safety notice. Owners should follow the manufacturer's current instructions.
