The short answer: For most serious DIYers and professionals, the DEWALT DCN680B is the better all-around cordless finish nailer due to its lighter weight, superior depth adjustment, and proven track record. However, if you’re already invested in Ryobi’s 18V battery system and need a budget-friendly option for occasional trim work, the Ryobi P320 is a capable performer that won’t break the bank.
Let’s break down the core specifications because they directly influence how each nailer feels and performs in your hand.
DEWALT DCN680B: It uses DEWALT’s 20V MAX battery system (sold separately). It weighs about 7.5 pounds with a battery, which is on the lighter side for a cordless nailer. It drives 18-gauge brad nails from 5/8 inch up to 2 inches. The magazine holds 100 nails, and it offers tool-free jam release and depth adjustment.
Ryobi P320: This nailer runs on Ryobi’s 18V ONE+ battery system (also sold separately). It’s a bit heavier at around 8.5 pounds with a battery. It also drives 18-gauge brad nails from 5/8 inch to 2 inches. Magazine capacity is 100 nails, and it features a tool-free jam release and a dial for depth adjustment.
The key differences: weight and battery platform. The DEWALT is nearly a pound lighter, which makes a big difference during extended overhead work or long trim sessions. Ryobi’s 18V system is vast and affordable, but the nailer itself feels bulkier.
Both nailers are designed to sink brad nails flush into typical trim materials like pine and MDF. In real-world use, they perform similarly, but there are nuances.
The DEWALT DCN680B uses a brushless motor, which provides more efficient power and longer runtime. It also has a dry-fire lockout that prevents dry firing and protects the tool. The magazine follower pushes the last nail firmly, and the depth adjustment wheel is precise, allowing you to dial in flush drives consistently.
The Ryobi P320 uses a brushed motor, which is older technology but still gets the job done. It tends to have slightly less power for the last few nails in the magazine, sometimes requiring a deeper trigger pull or leaving nails slightly proud. Depth adjustment is a simple knob, but it’s less fine-tuned than the DEWALT’s. For occasional use, the Ryobi is fine, but if you’re installing hundreds of feet of trim, the DEWALT’s consistency is noticeable.
Comfort is crucial when you’re holding a nailer for hours. The DEWALT DCN680B has a compact design with a rubber overmold grip that reduces vibration. The weight distribution is balanced, and the rafter hook is integrated nicely. It feels nimble, especially in tight corners.
The Ryobi P320, while comfortable, is heavier and feels more front-heavy. The grip is also rubberized, but the overall bulk can cause fatigue. The rafter hook is functional, but the tool sits differently on your belt. If you have smaller hands, the DEWALT is easier to manage. Also, the DEWALT’s belt hook is reversible, which is a small but thoughtful touch.
Battery life is a major consideration because you don’t want to stop mid-project to recharge. The DEWALT DCN680B with a 5Ah battery can drive roughly 500-600 nails per charge, depending on nail length and material hardness. That’s excellent runtime, thanks to the brushless motor.
The Ryobi P320 with a 4Ah battery will drive fewer nails, typically around 300-400, because the brushed motor is less efficient. If you’re doing a big job, you’ll need extra batteries. Also, note that both tools do not come with batteries, so you need to factor that into the total cost if you’re starting from scratch.
If you already own batteries from either platform, that’s a huge factor in your decision. If not, consider the long-term cost of the battery systems. Ryobi batteries are generally cheaper, but DEWALT offers more performance per dollar in the tool itself.
Durability is where DEWALT has a strong reputation. The DCN680B is built with a rugged housing that can withstand job site drops. It’s backed by a 3-year limited warranty, and DEWALT has excellent customer service.
Ryobi’s P320 is also durable for home use, but it’s not designed for constant professional abuse. Ryobi offers a 3-year warranty as well, but their tools generally have a lighter-duty feel. If you’re a pro who needs a tool that can take a beating, the DEWALT is the safer bet. For a DIYer who treats tools with care, the Ryobi will last years.
Yes, both can drive 2-inch brad nails, which is sufficient for most trim work. However, for dense hardwoods or very thick moldings, you might need a larger gauge nail. These are finish nailers, so they are ideal for trim, not for framing.
Typically, both come with a carrying case and a sample pack of nails. But it’s always best to check the product listing. The DEWALT often includes a belt hook and a non-marring tip, while Ryobi includes similar accessories.
For a beginner, the Ryobi P320 is more forgiving on the wallet, and if you already have Ryobi batteries, it’s an easy entry. However, the DEWALT’s lighter weight and precise adjustment might make learning easier, as you’ll have better control. If budget allows, the DEWALT is a more satisfying long-term investment.

Ultimately, the choice between the DEWALT DCN680B and Ryobi P320 boils down to your budget, existing battery ecosystem, and how often you’ll use it. If you’re a pro or a serious DIYer, the DEWALT is worth the extra cost. If you’re a weekend warrior who needs a reliable tool for occasional projects, the Ryobi will serve you well. Remember to consider the total cost of ownership, including batteries and charger, and choose the one that fits your needs best.
