I own the Lux model in .22 magnum. It is a beautiful, but dainty little rifle compared to my air rifles.
I too, was dissatisfied with the trigger from the factory. It had a gritty feel with excessive pull weight and creep. I polished and applied a light dab of moly grease to all pivot points of the trigger and sear and replaced the factory trigger spring with a lighter one. This made a world of difference to me. I can sense very little creep and a very light trigger. Probably around 1 1/2 to 2 lbs..
Also, the magazine fit loosely in the magazine well. I applied some JB weld to the back side of the magazine, which has seemed to take care of that problem.
Overall I am pleased with this rifle and would probably buy another if needed.
God Bless,
Scott
