I have shot barrels from 26" to 32" length & there are places & conditions where I like each. My all time favorite length is 28". This is mostly a matter of aesthetics. I am between 5"8" & 5"9" & well fitted by a 14" LOP. Aesthetically I think a shotgun looks nice when the barrels are around twice the LOP.
Much longer & it looks like something for a pole vaulter & much shorter it looks like a Coach Gun. With very, very few exceptions I "Personally" have little use for anything outside the 26"-30" range.
The 32" guns I have shot were 10lb + 10 gauges. For uses this type gun would be put to the 32" is fine, I "Personally" would not want a 32" or longer barrel in the uplands, Period.
