Ally McCoist's side gained revenge for their Ramsdens Cup defeat at the hands of the Doonhamers with a 3-0 triumph at Palmerston on Tuesday evening as the Third Division champs set up a semi- final encounter with Stenhousemuir.
It has been an impressive start to the campaign for the Light Blues, who have been bolstered by the arrival of a host of summer signings, with the likes of Nicky Law and Jon Daly shining for McCoist's team so far.
And Little is delighted to see progress being made as the SPFL League One leaders get set to put their 100% record on the line this weekend against Forfar.
"Coming out of the game, I think we're a little bit disappointed with how we played in the first half," the striker told rangers.co.uk
"But on the positive side, it shows how far we've come from last season, when we lost to Queen of the South in the same competition.
"That's the kind of game we would certainly have struggled with a lot more last season and it's an inidication of how much we've kicked on.
"It's maybe a sign of our fitness levels as well because we didn't hunt and chase in packs as we'd have liked to but we pushed on in the second half.
"We are capable of chasing teams and harrying them for whole games.
"Even if we don't have a lot of the ball, we've still got the legs to get round the pitch and there are very few teams so far this season who have caused us many problems in open play."
