The Shadow Systems DR920 Foundation pistol in 9mm and black finish (brand part no. SDWS SS-2306) is built on the same frame as every Shadow Systems pistol, delivering sleek ergonomics with real-world shootability and reliability. Shadow Systems fits the pistol with a 4.5-inch rifled, match-grade nitride barrel rated for +P ammunition, and a wraparound-textured grip with interchangeable backstraps dials in hand fit. The optic-cut slide accepts most major optic brands directly, with steel sights offering a lower 1/3 co-witness with most optics. Two Magpul magazines and three interchangeable backstraps ship with the pistol, which fits Glock 17 Gen4 holsters. Among optic-cut semi-auto handguns, this DR920 Foundation configuration favors shooters who want Glock-holster compatibility with upgraded internals.
