My first thought when I picked up the tool is that it feels heavy, and it is. Compared to dragging around air hoses or buying gas cartridges, a little bit of extra weight is okay. The weight is comparable with other nailers in its class, and Milwaukee packs in a lot of features that are easy to use and are well placed.
Some of the features include a metal tool-free drive depth adjustment, dry fire lockout, onboard hex key storage (hex key included), the previously mentioned no-mar tip and a rafter hook and belt clip, both nicely placed. The power button and sequential or contact mode buttons are in an easy to read spot on the rear of the handle. Milwaukee has also thoughtfully placed rubber anti slip areas on either side that would prove useful when nailing on roofs.
