ZEV Z19 DUTY SLIDE GEN 3 BLK RMR PLT The Duty slides feature the same worksmanship and quality that ZEV is known for with a functionally driven design and utilitarian coating for the no-nonsense shooter who is looking to complete a new frame build or to enhance the functionality of their Glock. The black nitride finish provides a durable coating and the patented ZEV RMR cut enables the use of red dot sights using an RMR installation footprint. We've reduced the cost, but not the quality. • Machined from 17-4 Stainless steel billet • Lowered ejection port to aid in ejection of brass • Match grade, precision milled tolerances that are tighter than factory • Improved accuracy and grouping performance upon installation • Torx wrench and two sets of RMR screws (tall and short) included
