The current fad for long barrels is of no more merit than the previous fad for short ones.

It just means that people were cutting down 30" barrels in the 1950s and now they are sleeving 28" guns to 32" because people will buy what is in fashion.

Remember when people were sleeving perfectly good 16-bores to 20-bore because of fashion?

Just musing a bit off track....
