The Foundation Series, constructed using the same frames as all Shadow Systems guns, boasts streamline ergonomics, exceptional shootability, and dependability in the real world. The distinguishing features include a wrap around texture with switchable backstraps and a slide with pocket cut serrations. It\'s designed with an optic cut, making it compatible for direct mounting with the majority of major optic brands. The steel sights come with a black serrated rear and a white dot front, allowing for a lower 1/3 co-witness with most optics. This series offers a rifled, match-grade nitride barrel that\'s optimized for +P ammunition. It also includes a carbon steel guide rod and a completely safe, polymer trigger. Fits flawlessly into Glock 17 Gen4 holsters. Included with the pistol are two Magpul magazines and three changeable backstraps.
