Machined from 17-4 stainless steel, each slide is built with tight tolerances to deliver increased accuracy and enhanced performance. Slides are available in a variety of colors and each slide ships with a black anodized optics cover plate with screws included. This is a stripped slide which will require the addition of internal parts, barrel, recoil assembly and sights. With a variety of designs and colors that fit a wide range of popular pistol models, Zaffiri Precision is sure to offer a top of the line slide that you will enjoy.
