The Henry, 1866, and 1873 use an "elevator". The cartridge slides out of the magazine, is lifted up with the round horizontal and then pushed straight into the chamber. The 92 uses a teeter-totter type lifter that can flip the cartridge. Unless you just have to have the Henry, I recommend the '66 or the '73 as they are easier to load. They have the loading port like your 92. The Henry loads from the front of the magazine tube. Plus the '66-'73 have a wood for-end, to keep you from burning your fingers on the hot barrel. The main difference between the ‘66 and the ‘73 is that the ‘66 (like the Henry) has a brass frame, the ‘73 is steel.
Personally I shoot the ‘66.
