Anyone else find it funny that nobody really complains about the Taurus locks?
Nope.
As a matter of fact I don't think I have ever heard or read about complaints about the Taurus lock. It seems to be very reliable and, imho, the best location for a lock. What I like best about it is about it is both hands and fingers stay well away from the muzzle and barrel / cylinder gap while gipping the gun properly. I suppose a user could install a hammer without the lock if it really bothers them.
The S&W lock added several small separate parts to the action that can become loose vs. the Taurus design where all of the parts are contained in the hammer. Anytime you add more small parts to any mechanical device you increase the odds of failure which in self-defense gun is a "come to Jesus moment."
I have not heard much about the lock on Ruger revolvers. Maybe it is because they hide it under the grips most folks don't use or even think about it.
p.s. Actually I do have a complaint about the Taurus lock. I brought a new Taurus snubbie several years ago that was bone dry of oil out of the box. I did not bother to clean or oil the gun and just took it out to the range to shoot it. After firing two cylinder full of ammunition the gun locked up but tight. It was not possible to cock the action, open the cylinder and turn the internal lock. A few drops of CLP working their way down into the action and lock freed everything up and the gun has worked flawlessly ever since.
I posted this on THR and the Taurus haters were quick to criticize the gun as a piece of junk. Using 4 or 5 drops of oil on a new gun is too much to ask (don't ask me how they don't use oil on their semi-autos and keep them working reliabily). I took it as a teachable moment for me to clean and oil all new and new to me guns before going to the range to shoot it.
p.p.s. To help pass the time on a long boring holiday shift at work last night I spent several hours cleaning and soaking a new to me single action revolver that was bone dry of oil. I used G-96 and gave the inside of the action a good soaking along with it cleaning a surprising amount of grime off of the outside of the gun.
It has a long cylinder pin with the two notches in it so when it is pushed all the way in it prevents the hammer from hitting the primer when loaded. This is easily deactivated merely by shorting the cylinder pin.
