Hi Drake.....welcome to TFF!
Bill.....Granted, "Suicide Special" (which referred to very cheap revolvers that were often as dangerous to shooter as to the intended victim) is a bit strong to apply the the low-end IJs.....
But how about the term "Saturday Nite Special" which referred to inexpensive revolvers at the bottom of the scale (which the low end of the IJ range (Model 1900 and the various tradename IJ-made revolvers...Eclipse, Encore, Favorite, Tycoon, etc.) certainly were. Wouldn't that apply?
Granted, they were a cut above many of the Belgian imports (and some American-made ones), but certainly a long way from the Colt of S&W quality range.
