The LF19 Combat Compensated slide features an integrated compensator. The integrated compensator reduces muzzle flip and makes follow-up shots faster and with more accuracy. Our 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 LF19 slide is precision machined in our manufacturing facility-made 416 stainless steel. Further, its heat treated to 38-42 HRC for optimal strength and durability.
