I do own a 94 and recommend it. The caveat is that if you can go with a bit heavier weighing gun the model then the models 970 or 990 should be looked at.
While the trigger pull is heavy things were slicked up by using .22lrf snap caps and doing some dry firing with the snap caps in place. This was about 90- 100 full cycles of the cylinder. This lightened the 94s trigger pull and smoothed things out.
I owned a older 20 year old 94 which worked well, but sold it to aquire a model 94 with the underlug.
The new 94 is the understudy gun to the centerfire Taurus revolvers. The 94 fires cheaper .22lrf ammo versus centerfire ammo.
I've had no problems with my 94.
