I also have a Taurus 94 w/ a 5" barrel.
DA pull is murderously hard. Close to 20 pounds, I'd guess.
SA break is okay though. It's pretty accurate, but I have noticed that the cylinder index notches are not deep enough. Squeeze the trigger too fast, or touch the wheel with your hand, and you can move the cylinder out of alignment so that you skip a chamber or you miss the rim of the cartridge and have no ignition.
I'd suggest sticking with a 6-shot model. Seriously. It's just a .22, it isn't a very good self defense round anyways. Any gun is better than no gun, but if you are buying this for defensive purposes, just buy a .38 instead.
Loading 9 rimfires I've found is a pain in the butt. I'd rather load 6. Out rabbit hunting, I've never needed more than 6 rounds at once. Target shooting, this gun is tedious to shoot 9 shots in a row since the frame is small and the DA trigger is so tight.
The problems with this gun could be fixed if it were of a larger frame geometry (GP-frame or L-frame), and the chambers were spaced farther apart so that the index notches could be deeper. Maybe the "tracker" .22 would be better.
Hope this helps.
