The P415 reliability has been tested time after time and the operating system perfected. Features E2 Extraction Technology, complete ambidextrous fire controls, modular free floating rail platform and numerous internal improvements make it the pinnacle of firearms. For the P415 Edge Pistol, weve cut the bulk. To minimize weight and maximize shooter comfort, POF-USA redesigned the MMR handguard. Not only does this drop the weight down to 6.5 lbs, it provides even better ergonomics to the shooter. This is a Piston Driven Firearm.
