Overview
The SL31 is a NuMax nailer weighing about 2.8 pounds, light enough for one handed use on trim and craft work. Beyond weight, this listing does not publish gauge, fastener length range or power source.
At under 3 pounds the SL31 is noticeably lighter than most cordless nailers, which points toward a pneumatic design meant to be fed by a compressor and hose rather than carry its own battery or motor weight. That light body helps with fatigue on long runs, though buyers should confirm gauge and fastener size against their project before ordering, since neither is listed here.

Who it's for
Works for hobbyists and light trim jobs where a small, easy to handle nailer matters more than raw driving power. Less suited to buyers who need a specific fastener gauge or length confirmed in advance.

Performance notes
A body under 3 pounds keeps arm fatigue down during repeated overhead or horizontal firing, which is the main practical benefit of a light nailer. The 4.2 star rating sits below the other nailer in this batch, so it is worth reading current reviews for recurring complaints before committing.
