CanAm, my suggestion for a barrel length is a little different, but it's something that I've personally been wanting to put together for awhile, just haven't had the time, money or parts. So besides the regular 10"(MCS style?),12.5"and 14" I'd offer the following;
Take the longer (5+1) mag tube of the Norinco HP9 hunting versions and have a barrel made flush with the end of that, should end up around 16" or so. Apparently if you replace the express style magazine spring retainer with the older Wingmaster style than it will actually hold 6 rds of 2 3/4" in the tube.
With this set up you can add a folding stock and still be over 26".
