Both of my Win. 94's, a .44 mag. and .356 Win. came with full length tube. They have a clamp that fastens the barrel and magazine tube together and a small screw about the size of a 8x40 going through the end of the magazine tube into the bottom of the barrel. On my Mod. 71 and Marlin 1895 I just have the small screw and no clamp and so far no issues.
You can order a tube and spring from several places, I think I used Midwest Gun Supply, just Google it. Any gun smith should find it and easy job to do. I always prefer a full length mag tube on lever guns, is there a better place to store ammo?
