I thought the "S" prefex stood for the new cross bolt safety as the orginal M1894 didn't have this feature. As I have a M1894S in .41 Mag 20", straight grip, full magazine made in the late 80s which has the cross bolt safety.
There is also the
"PG"- .44 Mag with pistol grip, 20"
"FG"- .41 Mag with pistol grip, 20"
"DL"- New Deluxe version being offered this year
You should be able to find a .44mag in 20". I have one, but it's a pre-1982 model, whatever that is. It has no safety and no checkering. I like it both of those ways.
The .44 you're looking for (it sounds like to me) is the "1894". You can check budsgunshop for prices though your local Walmart is likely to have the cheapest price to be found, outside of a major sporting goods store like Sportsmans or Cabelas. ANd even then, if they can beat Walmart, it won;t be by much.
