Their design engineers and product specialists understand tight tolerances, clean lines, and enhanced performance. But it is not just about style, its about giving you an edge. You get that edge by having a more positive ejection, a slide thats lighter, and you have an all-around smoother operation. They also are available with multiple aftermarket reflective sight cuts without requiring an oversized adapter plate. Every Glock slide is precision machined in 416 stainless steel. Further, its heat treated to 38-42 HRC for optimal strength and durability. If you want the best, look no further.
