The Beretta Guide Rod with Standard Recoil Spring is constructed from stainless steel and fits full sized series 90 pistols. Does not fit the 92A1, 96A1, and the 90-TWO. Does not fit Compact, Centurion, or Compact Type M Pistols.
This spring is now longer than the original but is the same weight. Due to supplier changes, the rod and spring may be chrome, stainless or black in color. Color differences do not affect performance.
