The SIG PE-57, civilian Stgw 57, is a robust roller-delayed blowback rifle chambered in 7.5x55mm Swiss. Its design, influenced by the MG-42, features a unique 'base-first' ejection system and a 'winter trigger' for cold weather use. Despite its weight, it offers a soft-shooting experience and impressive ergonomics.
