First off. I do not do roofing full time, I am a remodeler, I do a few houses a year. The guy I work with has the Hitachi NV45AB but we needed to have another gun this fall. I buy nothing but high quality tools, and most professional roofers use the Hitachi. I did a lot of comparing before I decided on this gun. The thing that got me was the price, I got a very good deal on this gun from the contractor tool store.
After using this gun and the Hitachi NV45AB on three roofs last month(about 100 square), here are my observations. (I have used the Hitachi for a few years)
The Milwaukee is lighter without a doubt, much nicer to carry around all day.
The nail loading mechanism is much nicer on the Milwaukee. You only have to open the feed flip, and the coil comes open too. The hitachi has a separate clip to open the coil, and it is underneath so you have to turn the gun upsidedown to load it. (that may seem like not a big deal, but when you are putting in a new coil every 5 minutes it is a big deal)(I believe hitachi's new nailer has the side load mechanism as well)
The rubber side grips are nice, it will stay on a 7/12 pitch.
You can move the shingle guide without an allen wrench.
It shot 1-3/4 nails much better than the hitachi.
I am not sure why they put sequential and bump firing modes on this gun. If you want to have any speed at all you will always use bump mode. Anyways, that isnt a problem, it just seems strange on a roofing gun.

It is comfortable to use, and I never had any jams. It comes with a nice molded case.

I was a little apprehensive about purchasing a tool that is brand new to the market, but having owned and operated various Milwaukee power tools for a number of years, and reading other reviews of this specific coil nailer, I decided to give it a go. I am a professional contractor and have used Porter Cable coil roofing nailers before trying the Milwaukee. I found the Milwaukee to be very smooth, and experienced minimal jams. It also required less air pressure to achieve proper nail driven depth, although this posed to be an issue as I was running Porter Cable nailers on the same line. I added an additional pressure regulator and took care of that problem. The bumpers on the gun proved to be useful a number of times and prevented the gun from sliding off the roof. I gave the nose attachment a whirl (for auto-positioning the nails by butting the attachment up against the shingle edge) but found it to be an annoyance as well as slowing me down. Coil changes were very easy - quicker and smoother than the Porter Cable. I'll replace one of my PC guns with another Milwaukee when it fails.

Recently bought this and have just finished two small roofs. ZERO jams, consistant depth (even with a "cheesy" compressor), and really easy to load and adjust. TRUTH IN ADVERTISING NOTE: This is my first roofing nailer, so I can't compare it to Bostich, PC, Senco..., but I'm really impressed with how well this one works. I expected some random problems, but so far have had NONE.

I ordered this nailer to reroof my house and it has worked flawlessly, it drives the nails to the same depth everytime and is easy to use. The selectable trigger is a nice feature. I would easily recommend it.

First off...my ownly complaint is the Milwaukee does not provide a quick release nipple to thjread into the air port. To complicate matters, the air port is not the commonly used 1/4 thread, but rather a 3/8 thread. So you need to locate and purchase both a 3/8 -to- 1/4 reducer bushing and also the quick release nipple. Once got past this problem, I was very pleased with the gun. It is light, easly to operate and well designed in terms of both selector switches for nail depth and sequential firing. Definately a very good value for the money.

this roofing nailer is nearly perfect. i couldn't imagine a thing to change. go to a good store and feel the difference in balance and feel to all the other tools. this one was lighter than every other roofing nailer that i tried, and many by a large margin. It shoots to a consistent depth every time too! Used it to roof a 2500 sf roof (used over 10k nails) and it didn't jam once, and very rarely (likely more my fault) it has a mis-fire

The first Milwaukee tool I ever used was a 1/2" drill built in the '70s. It was powerful, and always worked great. The first Milwaukee tool I bought was a Milwaukee Orbital Sawsall that will saw through anything with the proper blade. So when I needed a roofing nailer, needless to say, I knew Milwaukee made great tools. Let me say, I have not been disappointed with the 7120-21 Roofing Nailer. Whether you are a "do-it-yourselfer" or a professional contractor, you'll find this Milwaukee tool to be everything you'd want in a nailer. It is so simple to use and reload. It has never jammed. I would highly recommend anyone who is seriously considering buying a roofing nailer, to purchase one of these. You won't be disappointed as long as you use the correct nails.

This tool, no doubt, paid for itself during the first project. A great time saver and, without qualification, this is a real pro tool but affordable for a large diy challenge. Rather than hire done what I can do myself, I buy the tool with some of the savings. I usually get a higher quality result although the job takes a lot longer and now I own the tool. P.S. Consumer Reports rated this nailer one of the best values and I must agree after using it.

I bought this nail gun to roof my house. I have used many of them in the past with mixed results. The best of them were very heavy, the worst of them jammed so many times it would have been faster to use a hammer. This one was a real surprise to me however. It is the best of all worlds. It is very light, the size is great, and during my roofing project of 3000 sq ft. it jammed only ONE TIME!! (And I am certain it was my own fault.)
I found the nail depth adjustment pretty much useless, unless I was looking for a VERY small amount of adjustment. I found it is better to just drop your PSI about 10 PSI each time until you get the perfect depth you want. Other than that it was flawless. Easy to use, SUPER easy to load. I seldom ever heard my air compressor kick on, it is very efficient.
I was going to list it and resell it when I was done, but not a chance now. I will keep this thing until I die! I just used it again last weekend to reside part of my sisters house. Just adjust the PSI and leave the nails out a tad. Its accurate placement of the nails made the job go super fast. This one is a winner for sure, and WELL WORTH the cost of it. You wont be disappointed.

Have put a full box (7200) of nails through this, and so far no issues (other than cheap nails giving me a couple feeding issues). It fires nicely, and has kept up with the bostitch nailers that have been on the roof with it. On a side note, I was quite surprised at the quality of the goggles that came with the gun. I actually like to wear them.
