as jhm states, this is the way the WIN 94 is designed, enough pressure needs to be maintained on the lever, squeezing it to compress the little tab right behind the trigger. this insures you action (toggles) are completely locked up and wont allow the hammer to drop unless it is. The round feeding problem in the tube magazine, that sounds like you are inserting a round and allowing it to fall behind the side feed gate where cartridges are inserted. If more than one round is desired in the magazine, I usually insert a round about 3/4 of the way in, then with the next round, push it all the way in until this round is 3/4 of the way in, continue this until mag is full, then manually push the last round fully into the mag.
