gun barrel length is like ladies hem lines...they go up an down as styles change...

from a practical stand point, 25" barrelled guns were popular with grouse hunters for quick snap shots in heavy cover...

32" guns were all the rage with trap shooters...

skeet shooters used to like 26" guns...now they all seem to want 30" guns..

30" now seems to be the norm for sporting clays...

wunder watt will be the next fad...

keep it simple and keep it safe...
