Ruger 3521 Max-9 Long RD | 9mm | 4″ | 12+1

The Ruger 3521 Max-9 Long RD is a striker-fired, semi-automatic handgun chambered in 9mm Luger with a 4-inch barrel and an optic-ready, serrated slide. It pairs a black polymer frame with alloy/steel components for a balanced service-style profile and carries a 12+1 capacity. For a compact red-dot that pairs well for duty-style carry and range accuracy work, consider a Trijicon RMR Type 2 — a proven micro optic under $1,000 that complements the Max-9’s optic-ready slide.

Applications include everyday carry (where allowed) and precision-focused range training or competition practice. The controls and sighting options make the Max-9 suitable for shooters seeking a modern striker-fired pistol with optics capability.
