Why would you cut barrels when there are so many 26 inchers out there already and they sell for less than longer barreled guns. I would look for a fast handling gun and 26" barrels usually means faster. Chokes could be cut by Mike Orlen. He charges somewhere around $40/choke and he is good at turning your chokes into cylinder. Maybe the left barrel should have some choke for longer shots.

So many guns, so little time!
