Overview
The Ryobi P321 is one of the stronger-reviewed cordless nailers in this batch, earning a 4.4-star rating from 807 verified owners at $109.68. That review count sits well above most other cordless options here, providing a meaningful data set for assessing real-world performance. Monthly demand of 50 units is modest but consistent.
As part of the Ryobi ONE+ platform, the P321 is designed to run on existing Ryobi 18V batteries, which reduces the incremental cost for buyers already in the ecosystem. The listing does not publish weight, nail gauge range, or drive speed, but 807 reviews at 4.4 stars suggest the tool performs reliably for the trim, molding, and light finish work typical of residential DIY projects.
Compared to the Ryobi ZRP320K1 in this batch, the P321 has a stronger review base (807 vs 395) and a slight rating advantage (4.4 vs 4.5 is close), with a lower price ($109.68 vs $156.99). Buyers comparing the two should note the P321's better demand signal and lower cost.
