Piper M350 vs Piper M500 vs Piper M600 Sls

The Piper M350 is the entry point of the three, positioned as a pressurized piston single. It typically offers the shortest range of the group and is best suited to regional trips; in practical terms it generally supports about five to six occupants depending on load and fuel, with seating for up to six in the cabin. The Piper M500 moves into the turboprop category, bringing higher cruise speeds and a meaningful step up in usable range versus the M350. Passenger capability is similar in layout—commonly flown with four to six aboard—but the turbine performance makes it better for longer legs and higher-altitude weather. The Piper M600 SLS sits at the top as the most capable turboprop in this lineup. It generally delivers the longest range and greatest payload flexibility, so it’s the most accommodating for carrying more people farther with bags and reserves. Like the others, it’s a single-engine pressurized cabin with up to six seats, but it tends to retain that capacity with less compromise on fuel and payload than the M350 and M500.
