What a stupid video. I hate these videos where the author blabs for three minutes, including a stupid supposed argument, before he gets down to business.
ALL revolvers imported into this country are required to have some sort of safety mechanism. ALL OF THEM!
Colt gets away without any sort of safety mechanism because they are manufactured in the US, and are not imported.
For a number of years Uberti was making a revolver that had a small hammer block incorporated into the hammer mechanism.
This is the type of hammer that had the built in hammer block that Uberti was importing years ago.
After a while, Uberti switched to the type of cylinder pin that engaged the spring loaded latch with two positions on the pin. When the pin was pulled all the way back, the rear of the pin extended out through the rear of the frame, and blocked the hammer from falling all the way. I suspect Uberti did this simply because it was less expensive to install the two position cylinder pin than the extra machining and extra parts needed for the earlier style hammer with the built in hammer block. The two position pin was a useless safety device, because it could not be easily manipulated with one hand if the revolver needed to be fired in a hurry. So the shooter had to always remember to keep the stupid two position cylinder pin pulled to the forward position if he wanted to fire the revolver in a hurry.
I bought this Uberti Cattleman slightly used about 20 years ago. It came with the stupid two position cylinder pin, which I immediately replaced with an aftermarket cylinder pin with just one position.
For what ever reason, probably as stated to avoid lawsuits, Uberti redesigned the mechanism to the current 'three click' version. Another stupid name. Let's be clear here. The reason the traditional Colt type action has 'four clicks' is because an audible click is heard when the hammer is pulled back to the so called 'safety cock' position, another click is heard when the hammer goes to half cock, a third click is heard when the bolt pops up against the cylinder, and the final click is heard when the hammer goes to full cock and the bolt pops into a locking slot. If one cocks a Colt or clone very, very slowly, one might actually hear five clicks, because the hammer may go to full cock slightly before the bolt pops into a locking slot.
With the 'three click' lockwork, the so called 'safety cock' notch on the hammer has been eliminated. So the first click heard will be the hammer going to half cock, then the bolt pops up, and finally the hammer goes to full cock. Just three clicks.
The new safety mechanism that Uberti incorporated relies on a retractable firing pin. The firing pin is held in the retracted position by a small spring. In the retracted position the firing pin cannot touch a primer. With the hammer at full cock, when the trigger is pulled, an extension on the trigger pushes a small actuator inside the hammer up, which in turn wedges the firing pin forward, so it can strike a primer as the hammer falls. One can cock the hammer and pull the firing pin forward, but the internal spring will pop it back to the retracted position in the hammer. Only by pulling the trigger will the actuator wedge the firing pin forward to fire a cartridge.
Here are the lock work parts of a 2nd Gen Colt Single Action Army. The parts of the old 'four click' Ubertis are basically the same. Except for the very earliest 1st Gen Colts, the firing pin can wiggle a little bit up and down. The firing pin is held in place by the rivet seen in this photo. The firing pin is purposely allowed to wiggle up and down a little bit because the firing pin has to 'find its way' through the firing pin hole in the frame. This is because of the geometry of the arc the tip of the firing pin travels through as it flashes through its hole in the frame. So it is purposely allowed to wiggle up and down a little bit, pivoting slightly on the rivet.
By the way, this photo also illustrates why a Colt or clone must NEVER be carried fully loaded with a live round under the hammer. Notice how thin the tip of the trigger is, where it engages the cocking notches on the hammer. Even with the trigger in the so called 'safety cock' notch, it would not take much of a blow to the hammer to shear off the tip of the firing pin, or the cocking notch, allowing the firing pin to strike a primer, and discharging the firearm.
Regarding why your shots are going low, I have no idea. I always line up the top of the front sight blade with the top of the rear sight, and hold at 6 O'clock on the target.
By the way, most of the imports replicate the tiny V groove rear sights of the old 1st Gen Colts. I much prefer the nice squared off rear sight of a 2nd Gen Colt, on the left in this photo, to the tiny V groove of my old Uberti Cattleman. Much easier for my 72 year old eyes to see the sights.
