Underwood Ammo .357 Sig Handgun Ammo - 65 Grain | Xtreme Defender

The Underwood Ammo .357 Sig Handgun Ammo - 65 Grain | Xtreme Defender is a high-performance ammunition that offers unparalleled stopping power and penetration. Designed with the popular Xtreme Penetrator product line as a base, the XD ammunition features an optimized nose flute, total weight, and velocity to achieve a remarkable penetration depth of up to 18 inches*.

What sets the Xtreme Defender apart from other expanding hollowpoint bullets is its permanent wound cavity (PWC) that is over 100% larger than any other expanding bullet. This expansion is achieved even when shot through barriers such as wallboard, sheet metal, and automotive glass, thanks to its solid copper body. The Xtreme Defender delivers a devastating blow to the target, leaving a massive wound channel that ensures optimum stopping power.

Not only does this ammunition offer exceptional performance, but it also provides reduced recoil. The CNC machined solid copper construction allows it to overcome barriers to penetration, while the radial flutes force hydraulic energy inward to build pressure. The minimal surface area and sharp cutting edges at the point of contact increase the force for maximum impact and defeat barriers effectively.

In addition to its superior performance, the Underwood Ammo .357 Sig Handgun Ammo features nickel plated casings. This innovative nickel plating process offers several key benefits, including improved feeding in all firearms, enhanced corrosion resistance, improved cosmetics, and ease of cleanup during reloading. Unlike brass casings, nickel plated casings do not tarnish during storage or when in contact with foreign materials. With the new Ducta-Bright 7a process, concerns about embrittlement and failures are eliminated, making these casings safe and reliable for multiple reloads.

As with all Underwood Ammo rounds, this ammunition also utilizes flash suppressed powder to ensure your vision is not compromised in low light conditions. It is field-tested using popular real firearms to guarantee its performance in real-world scenarios.

With Underwood Ammo, customer satisfaction is paramount. If for any reason the ammunition fails to meet performance expectations, the company stands by its product 100% and ensures the customer is satisfied with every purchase.

The Underwood Ammo .357 Sig Handgun Ammo - 65 Grain | Xtreme Defender is new production, non-corrosive, and comes in boxer-primed, reloadable brass cases. With a muzzle velocity of 2100 fps and muzzle energy of 636 ft. lbs., this ammunition delivers impressive power and penetration with a penetration depth of 17.5 inches.
