He's only 4 months old - he has a LOT of growing left to do! It's way too soon to worry about his weight, and it really shouldn't be a concern anyway. You can't make him any bigger than he's genetically predetermined to be, and feeding more to try and make him grow faster is just going to make him fat.
At 6 months old my boy Keefer was 7 pounds less than his half sister was at the same age. As a male he should have weighed MORE than she did at 6 months old, but he grew at a slower rate than she did. At adulthood he ended up outweighing her by nearly 10 pounds - he's 80 pounds, a little over the mid-range of the standard for a male, which is approximately (converted from kgs) 66-88 pounds.
If he's healthy, his stools are normal, and he's continuing to grow, you really don't need to worry about his weight.
