By Woodworking Engineer
“I bought this for trim work for my home office remodeling. I have a Porter cable 18 awg and a Grex 23 awg. I am happy with this one also. It has plenty of power, but I can still use it with a three gallon compressor and get plenty of shots before the compressor recycles”

By Robert Norman 
“I love this nailer, easy to use and dosent jam often. I have shot a couple thousand rounds through this gun now and I love it. I did have one jam in that time but the tip unlatches quickly making it simple and quick to unjam. Comparing it to my bostitch this one wins hands down”

By Mike Serafin 
“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”

By Sean Seebran 
“This is definitely one of my favorite tools in my workshop. I also have a Porter Cable (FN250C) which also worked great until recently when the trigger valve started to leak, so now it needs to be overhauled. I thought that I would purchase a new nail gun while the overhaul kit is on the way for the Porter Cable.

I decided to purchase this model because it uses the same size nails as the Porter Cable so I can use the same size nails with both and switch them out as needed without hurting production. I’ve always had great luck with Dewalt tools as none that I own has ever failed to date. If you are looking for a great finish nailer, you can be confident that the Dewalt (D51257K) will be a great addition to your shop.”
