The DeWalt 16 gauge finish nailer makes an excellent addition to one's collection of finish nailers, either as a homeowner or a professional. One of the benefits of the 16 gauge nailer is that the nails are much cheaper than the 15 gauge nails. With that said, the 16 gauge nails lack some of the holding power and are more prone to blowouts (which can be easily avoided with correct usage) because they are stamped and rectangular instead of round. Don't let that discourage you, however, because the 16 gauge nails have plenty of holding power for applications like interior door jams or holding up heavy crown molding.
The DeWalt nailer is nice in that it can be used without oil; however, it is still best to give it a light oiling once in a while to ensure that it lasts. I have no doubts that it will last. The tool consistently countersets nails to the right depth and has plenty of power (I keep the compressor around 100 psi). I've never had a jam, but the release on the front for jams is easy to open. The depth adjustment is the normal wheel mechanism that allows for very precise adjustment. The no-mar pad works very well, and nail placement is easy to see. Case is sturdy and securely holds the nailer as well as some space for nails and safety glasses. I found the loading very awkward. The two methods used to load seem arbitrary and more of an advertising scheme than anything else. DeWalt could have designed this function better, but I've not found it too bothersome to deduct a star since the overall performance is excellent. Also, the manual is map-style instead of book-style (feels like 12 feet by 10 feet large), which is a real pain to use if you're unfamiliar with pneumatic tools, but this seems like a minor detail.
I highly recommend this tool.

I used this nailer while installing 800 square feet of hickory flooring. It was used to face-nail the starting and ending rows, to get in closets where the flooring nailer couldn't reach, and to install the baseboard molding. I only had two jams out of 1500 nails. The jams were easy to clear thanks to DeWalt's easy opening jam clearing thingy. (that's the technical term!)
The depth control wheel right on the nailer makes it easy to put the nails where you want them.

Used to install new base trim all around my house. installed over 1,400 linear feet worth of trim and never had a jammed nail.
Great gun to use; sinks the head everytime and wont mark up the trim being installed.

I would happily give this nailer 5 stars if it cleanly ran 2.5" nails. I've run 1.25, 1.5, 2, and 2.5. The first 3 run seemlessly. The 2.5" need help feeding in the magazine. If you assist the feed, they fire clean.

For reference, I was running Dewalt branded 2.5", so I can't blame it on some of brand that Dewalt wouldn't have tested. Thankfully, I mostly run 1.25 and 1.5", so it just slows me down occasionally.

Good power, no misfires, easy to clear out jammed nails; balance is good, complements my Dewalt 18 G gun. Study carrying case; gun is absolutely what I require for my trimming gun assortment. (15G,16G,18G,pin) .Outperforms in replacement in this catagory (porter-cable 16). Would recommend it highly.

This finish nail gun is the worst I've ever had or used. I purchased this based on prior purchases of Dewalt products of which I have many. Out of the box it delivered 2 nails every few nails and jammed each time. The Dewalt was to replace my Porter Cable gun that died after 21 years of faithful service. After the DeWalt failed I considered buying another Ported Cable, but alas they are made by the same company with the same nose configuration so instead I ordered a Bostich. The Bostich I received today and with limited use it appears to work fine.

Awesome nailer. DeWalt quality feel throughout, and super easy to load the nails. runs a 2.5 inch nail all the way through seasoned red oak with no problem. I've found uses for it I never expected when I bought it for baseboards. My only complaint is that it does not tell you when you run out of nails - it sounds the same and feels the same shooting nails or blanks, and if the depth is set to countersink a bit, you might not notice right away. It would be nice if it somehow would stop working when empty. I've not used others to know if that is common or not. But the nails are clearly visible, so it just taught me to keep an eye on my supply so I don't run out!

I enjoy using the Dewalt D5125K nailer. This is the first air nailer I have owned. It sure beats pre-drilling holes and driving nails by hand. Occasionally, the tool does not fire. This seems to be when the nails are not in the chamber exactly straight.
