M98 Widow and Javelin

On masseffect.wikia.com and other sites it is writen that M98 Widow is stronger than Javelin (Single Player mode) I have a strange thing, because Javelin in my game deals more damage and weight more than Widow in every weapon level. No matter is 1 lvl or 10 lvl, Javelin is always stronger and heavier. My version of game is 1.05, i have all DLC, without mods. Is bug or something like that?

I checked in coalesced.bin but everything is all right - Jav deals 993 on X lvl and Widow 1086 on X.
