The Polymer80 Standard Slide is constructed of domestically-sourced 17-4 PH stainless steel, heat treated to 42-43 HRC and then evenly coated in 360 degrees with high performance DLC (Diamond-Like Carbon, an amorphous nanocomposite coating) for ultimate durability, lubricity, and wear resistance. Aggressive front and rear serrations coupled with clean, modern lines and a heavy front chamfer allow effective manipulation and holstering of a PS9-equipped pistol while maintaining a low-key aesthetic profile. The PS9 Slide is compatible with the Gen 3 G19 platform and will be the perfect way to complete your Polymer80 PF9 pistol build or as an upgrade to your existing OEM configuration.
