I took this gun to the range for the first time. I noticed it is very difficult to load the shells in the mag tube, then after about 25 rounds it jammed.
I had to leave the range with the lever locked open, and a shell stuck about 3/4" out the mag tube. Luckily the chamber is empty. The lever will not budge, and I think I still have 2 rounds in the tube. Before I blow money at a gunsmith, any suggestions?? If not, I am going to dissassemble gun to see if shells will come out. My first impression of the Marlin 1894 44 mag is not good!!

I disassembled the gun. It still had 5 rounds in the tube. The shell involved in the jam is deformed now. I am going to clean this gun, oil it, and put it back together. If I am not happy with it's performance, I will then give someone a **** of a deal on it!!

I had the same problem with my 1894 ss 44 mag last week. It was really sticky without loading it so I went thru a few dry cycles and yep it got stuck, it was locked shut. I got it open but it jammed again. I took it back and they got it going again. The gunsmith said it had way too much grease and oil in the action from the factory, he cleaned it up and it is better now. Try taking it down as in the manual, put some gun scrubber in the action then oil. It seemed to help mine.

The cartridge gate screw was loose. I think that may have been causing the jam. I will ensure that it is tight when I reassemble.
