The Winchester Super-X Pistol Ammo 40 S&W 155 gr. Silvertip HP delivers the trusted Silvertip series performance shooters and defenders have relied on for decades, combining a 155-grain Silvertip jacketed hollow point design with a 1205 fps muzzle velocity and roughly 500 ft-lbs of energy to provide controlled expansion and reliable terminal performance for home defense and duty applications. With brass casings and a United States origin, this load feeds consistently in compact and full-size 40 S&W pistols and offers shooters a confident balance of penetration and energy transfer where stopping power matters most. The Silvertip model is built to manage recoil and follow-up shots, making it suitable for defensive carry, duty use, and realistic defensive drills at the range, while the hollow point profile helps reduce over-penetration in populated environments. Packaged under Winchesters long-running Super-X line and marked for safe transport, this round is a go-to choice for those who want a proven defensive pistol cartridge with predictable performance, dependable feeding, and the ballistic numbers to back it up.
