Ever since Dad gave it to me almost 20 years ago, I have loved the little B92 .44 Mag. Not only is it accurate, its lightweight makes it a joy to carry in the woods.
For many years this rifle was my backup elk rifle, and each year I made it a point to hunt with it at least one day during elk season. I only had two complaints with this rifle - my eyes are old enough that using the iron sights was getting to be a pain, and according to the manual, the trigger was set to "about 5-1/2 pounds" at the factory. I suspect the trigger was actually heavier - it felt more like 6-1/2 which is what my Marlin 375 was at before I replaced the trigger on it with a WWG trigger.
The sights were taken care of by simply scribing a horizontal line on the rear sight and filling it with white paint, then painting the front sight with white paint as well. The trigger pull issue went unresolved until yesterday.
I've been tuning up the triggers on various firearms since my wife gave me a Dremel tool for Christmas. Yesterday morning I tackled the B92. It turned out the solution was really simple and quick. Removing a single screw allowed the buttstock to slide off, then removing the hammer screw allowed removal of the the trigger assembly and hammer.
Careful inspection of the mating surfaces on the hammer and trigger convinced me that they were not the problem -- they were already well polished nd the angles seemed to be correct. The problem seemed to be almost entirely in the "u" shaped trigger spring.
After carefully reviewing the function of the trigger mechanism, and making sure I understood how the various parts interacted, I took a small screwdriver and slightly bent one of the two legs of the trigger spring. To test the effect, I put the hammer back in the assembly and dropped the hammer spring through the holes to hold it in place, then put the hammer spring in place. The trigger was better, but still heavier than I wanted. I removed the hammer and carefully bent the second leg of the trigger spring to match the first, then gently polished the mating surfaces on the trigger and hammer. I then replaced the hammer,hammer screw and hammer spring and re-tested the trigger . Beautiful!
After disassembling the trigger assembly one more time, I cleaned all the parts and used a toothpick to apply a tiny amount of silicone grease to the sear parts and other wear/bearing surfaces. Reassembling the entire rifle only took a couple of minutes.
Final testing with the fully reassembled rifle left a big smile on my face -- I don't have a trigger pull gage, but I'm guessing about 3-1/2 pounds, crisp, clean and short.
Had I known how easy it was, I would have done this years ago!
