change the range of the model 1887

I wonder if it is Possible, and if it is, how to make this alteration.
The Model 1887 was unfairly nerfed, they range was lower than the 12 spas, they only managed to fire more rapidly (switching between weapons).
Today, akimbo is a crap, and she alone with fmj, has shorter range than the spas, and shoots more slowly ..
I just wanted to increase its reach, it is a very stylish weapon to use ..
thanks!
