I would check that information out real close! I don't believe the action on that model is weak compared to the 1895 45/70 or the .444 Marlin.
Unless the word "don't" is a typo above, you are dead wrong.
The 1876 Winchester is a WEAK toggle link locking action just like the 1860 Henry, 1866 and 1873 Winchesters.
It's not NEARLY as strong as an 1886 Winchester or 1895 Marlin.
