195 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The RYOBI P321K runs on an 18-volt battery, which means no compressor or hose to manage on the job site. At 6.5 pounds, it sits in the mid-weight range for cordless nailers, acceptable for bench work and framing trim but noticeable during sustained use above shoulder height.
At $169.90, it carries a modest premium over comparable cordless nailers. Based on specs and verified owner reviews, 195 ratings averaging 4.3 stars confirm steady satisfaction among buyers who appreciate the freedom from air lines. The 50 units sold per month reflects solid but not high-volume demand.
For homeowners completing trim work, baseboards, or cabinet installation as part of a RYOBI toolkit, the P321K makes sense. Buyers outside the RYOBI ecosystem may find similar performance at lower cost by considering other 20V platforms.

- Published specs do not list nail gauge range or nail length capacity

Performance notes
Battery-powered at 18 volts, the P321K does not require an air compressor. The 6.5-pound weight is typical for cordless brad nailers in this voltage class. No RPM, SPM, or drive depth specs are listed, so performance comparisons to air-powered models should rely on owner reports.
What buyers say
Owners generally praise the cordless convenience and battery compatibility with other RYOBI tools. The most common concern in reviews relates to weight during extended sessions. Overall satisfaction tracks with the 4.3-star rating across 195 reviews.
