Nothing great can be built without a solid foundation. The XR920 is a crossover pistol with a full-size frame and a compact top end with capacity for 17 + 1. The Foundation Series by Shadow Systems developed out of conversations between old-school gun guys, the type who aren’t fussy about aesthetics and want only the essential features. Built on the same frames as all Shadow Systems pistols, the Foundation Series touts sleek ergonomics, real-world shootability, and bet-your-life reliability.
