Your rifle has the same sight geometry as a Winchester 94, and ergo can use the same sights.
For better dim light sight pictures, I would install a set of Williams open FireSights (Williams/Midway/Brownells), or Tru-glo's (Cabela's).
If your particular Model 92 has standard dovetails, the sights should slide right in, with maybe a bit of minor fitting - and if it has the oversize dovetails some do, pop a BCS (beer can shim) under the dovetails to tighten them.
