Right tool for the job - Trijicon Rmr Mount W/ Integrated Bright & Tough Night Sights - Sig Sauer M17/m18 - Commercial

Tried to save some money and bought a third-party plate; that was only a little cheaper than this, that failed, and nearly lost my rmr in the process. Bought this plate and significant difference between the two as this is steel, and I believe the other was aluminum. (Steel screws, aluminum plate, and recoil don't mix well) With a steel plate, everything has been rock solid since mounting it. Should have bought this in the first place.
