The Springfield Armory XD was introduced in the early 2000s and quickly established itself as a reliable and affordable option in the polymer pistol market. It is a full-size pistol, standardly equipped with a 4" barrel, which provides a balance between ease of carry and performance. The XD is designed for durability and ease of use with features like a grip safety, a tactile loaded chamber indicator, and a striker indicator. The XD set the foundation for Springfield's modern line of handguns by offering superior ergonomics and a user-friendly design, making it ideal for both new and experienced shooters. Its polymer frame and striker-fired mechanism were built to meet the demanding standards of "eXtreme Duty," hence the XD name. Available in various calibers, including 9mm, .40 S&W, and .45 ACP, the XD offers versatility to suit different needs and preferences. The original XD model is also noted for its drift-adjustable durable sights and its capacity, which is competitive within its class, providing a solid choice for both personal defense and law enforcement use. The Springfield Armory XD Defender series, also known as the Defend Your Legacy Series, offers a value-oriented approach to the classic XD line.The XD Defender models include features like a Melonite-finished slide, a grip texturing that mirrors the standard XD models, and a single flush-fitting compact magazine. They come with essential features such as forged frames, striker-fired mechanisms, and the Ultra Safety Assurance (USA) Action Trigger System.
