I have checked out trigger jobs done by pistol smiths. They say well tuned triggers break like glass. The ones this local smith had didn’t break at all to my feel. I touched the trigger could feel the hammer fall but could not feel the trigger as there was a trigger stop which stopped all trigger movement at the point it broke. My SAA is extremely light but at least one gets a little feedback from the trigger. People tell me I am wrong and that is the proper action for a supperior target gun. Sorry but not for me.
I have two rifles with set triggers. There is a second trigger device which sets the main trigger to be a hair trigger. As you don’t set the trigger till you are on target it is not a safety issue, but boy it is extremely light.
I have never owned anything with a trigger that would qualify. But much can be said for having proper technique.
One very convincing demonstration at a class I took was having the student take his stance and bring the sights on target. The instructor would then place his own trigger finger over the trigger finger of the student. Then the instructor would supply the pressure to fire the gun while the student held on target.
The result was startling, especially for the unskilled students. The rounds were within the small black square at the center of the target. The instructors were pretty good.
I was firing a standard Glock .45 and was impressed with how accurate the gun was when operated properly.
