Overview
Air powered and weighing 8.25 pounds, the Craftsman CMP21PL nailer runs without a battery. It holds a 4.4 star average across 120 reviews.
As a pneumatic tool, the CMP21PL needs an air compressor and hose to run rather than a battery pack, which keeps it lighter at 8.25 pounds but ties it to a compressed air source on the job site. That tradeoff is worth weighing against cordless nailers if working away from a compressor matters more than raw drive power.
