I have a 48-4 that I have done some action work on. The best thing I can tell you is you can improve the DA pull, but don't expect it to be as light as a centerfire, it ain't gonna happen. The 22 mag takes a solid strike of the firing pin to fire, so you can experiment by reducing the mainspring tension until it becomes unreliable, and then turn the screw back in 1/2 turn, loctite it, and you should be good to go.
Also, some brands of 22 mag ammo are more sensitive than others, so remember to experiment with brands also.
The trigger rebound spring can be cut, or replaced with a reduced power spring also, again you will have to experiment to see how your 48 likes what you are doing.
My 48 is a range gun, so An occasional misfire in DA doesn't bother me, as I shoot it SA most of the time.
Lastly, remember to brush the chambers often, and brush under the extractor, you will get along a lot better with misfires by having it clean.
