To lift the mag disconnector lever off of the frame, use a small screwdriver and pry it upwards. The coil spring is underneath. The disconnector lever has a small slot cut in the shaft for one end of the spring. You will have to pull the spring out of the frame until the straight edge sticks out about 1/8th inch. Slide the disconnector lever onto the spring end so the arm points in the six o'clock position. Only slide on the disconnector part way, then rotate the arm counter clockwise to about the three o'clock position and push it all the way down into the frame. You will have to push the trigger bar downward for the lever to fit completely in the frame. When disconnector is fully installed, it locks the trigger bar in place in the trigger bar slot. The lever keeps the trigger bar engaged with the tab on the sear. If if the mag disconnector is not fully installed, then the trigger bar can slip off of the sear tab and cause a problem like you've described with inconsistent hammer releases. You may have to try a few times to install it right.
Once you get the mag disconnector on correctly your problem should be solved.
Hope this helps.

Whew! Thanks Bullseye for all your help.

Obviously, I got a pistol that somebody had given up on. Their loss.
Couple of questions regarding the 41's:
Is it OK to drop the slide using the slide release?
How about VERY LIMITED dryfire.
How normal is it to find a 41 that cycles most everything? You hear all the stories of 41's that won't cycle anything but CCI SV, or Greentag.
Again, thanks for everyone's help and patience.
