To create the XD-S Centerfire Pistols, Springfield Armory took the best innovations of the award-winning XD Series and trimmed down the frame to a perfect size for compact, concealed carry. Metal parts on each gun are forged and machined from billet with utmost precision. Fully hammer-forged barrels enhance accuracy. Corrosion-resistant finishes are either super-hard black Melonite® or classic bead-blasted stainless steel. The Ultra Safety Assurance Action Trigger System™ guards against accidental discharge by locking the trigger in place until direct rearward pressure is applied. Loaded-chamber indicator allows the shooter to verify without a doubt, visually or by touch, that there is a round in the chamber. Grip safety allows firing only when the shooter has a firm grip on the pistol. A more pronounced texture on the XD-S ensures your grip is always secure. A single-position Picatinny rail readily accepts lights, lasers or other pistol accessories. It is one of the only polymer pistols of this size with this feature. The XD-S trigger has a short travel along with a short reset, which keeps you on target with greater ease for quicker, more accurate follow-up shots. The low-profile rear sight is holster friendly. Fiber-optic front sight promotes easier and faster target acquisition. Customize your grip with two interchangeable backstraps. Includes rugged carry case, paddle holster, double magazine pouch, two interchangeable backstraps, two magazines, cable lock, bore brush and safety manual.
Sortve, it doesnt have a switch style safety, but it has a Grip safety, a firing pin block and their "Ultra Safety Assurance (USA) Action Trigger System". Info here: springfield-armory.com/products/xd-s-3-3-45-acp/
