Some of these weapons unlocked have poorer stats than the previous weapons.... i've got 3 shotguns for the custom loadouts but the first still has the best stats easily. (admitedly though I am terrible with shotguns so i'm not too fussy)
P99 is the other example I can think of, which is overall poorer than the Torka... though I have now just unlocked the Hawksman which is apparently a bit better (not tried it yet)

Last few hours of play i've been trying to use the other weapons to gain some XP, i'd already maxed the Sigmus9 then converted to the Stauger and maxed that, and using the Kallos occasionally meant I had maxed that. Now i'm trying to use the Sigmus, one of the shotguns, the AK-47 or the Pavlov when I can (generally when I feel confident enough with the map chosen to use a specific weapon)... made me realise how much of a dog the AK-47 is (so innacurate) as well as how horrible I am with shotguns, I think only once or twice have I managed to eliminate more than die in a match using a shotgun.
