MY 390 came with three tubes, IC, M and F. It is 3" chambered. It does not have a recoil pad installed, nor the stock adjusting shims. It points great--I shot a 23 on the trap my second round with it--after a 15 year layoff.
Mine was the last display model--several scratches and label goo. The manager knocked down to $450. When I got home, it cleaned up nicely.
