What you have pictured is a replica of the original Colt Bisley design. The grip shape is significantly different than the Ruger version of the Bisley grip.
This is an original Colt Bisley. It left the factory in 1908. The Uberti replicas are very faithful copies of this design. Notice how far forward the grip sweeps at the bottom.
This is the Ruger version of the Bisley grip. Notice it is much more straight up and down than the original Colt Bisley grip.
The Bisely Colt was named after the Bisley Range in England, where international shooting competitions took place at the end of the 19th Century and beginning of the 20th Century. For years, S&W Top Break revolvers had been winning most of the trophies. Usually the New Model Number Three, such as this one.
In 1894 Colt introduced the Bisely version of their Single Action Army as a target pistol to compete with the S&W designs. This photo shows how different the standard Single Action Army design at the top of the photo was from the Bisley model at the bottom.
My experience shooting a traditional Bisely style revolver is that because of the forward sweep of the bottom of the grip, it tends to point slightly down, rather than straight forward. I have always assumed this was because many 19th Century target pistol shooters fired their revolvers with a slightly bent elbow. With a slightly bent elbow, the Bisley points straight forward, rather than slightly down. Most target shooters today shoot with a straight elbow (bullseye style), so the original Bisely grip may tend to point slightly down for them.
Regarding the quality of Uberti revolvers, in my slightly biased opinion the quality is better than a Ruger. Rugers are mass produced and designed so that an absolute minimum of fitting is required to assemble them. They truly go together with almost no fitting. Take a really close look at your Ruger and you will see there is a slight mismatch of the grip frame to the frame. They are all like that. It is not a big deal, the gun will function fine, but Uberti and Colt grip frames are ground to final shape together so there is no mismatch to the fit of the parts of the grip frame to the frame. Ubertis are pretty much made the old fashioned way, with forged and machined parts, and may need a bit of fitting at final assembly to get everything to work properly.
Of course, as everyone will tell you, Rugers are built like tanks. Although Ruger's advertising will not state this, most Rugers, with the exception of the New Vaquero, can take 'Ruger Only' loads. An Uberti replica cannot. Then of course, all Rugers have a transfer bar inside, so they are completely safe to carry fully loaded with six rounds in the cylinder. Until recently, Uberti revolvers were not safe to carry fully loaded, they had to be carried with five rounds in the cylinder and the hammer down on an empty chamber, no different than a Colt. This was to prevent an accidental discharge in case the revolver were to fall and land on its hammer.
More recently, Uberti had incorporated a retractable firing pin in the hammer, that only extends fully when the trigger is pulled. These modern Ubertis are safe to carry fully loaded, but some shooters object to the diversion from the traditional Colt design.
No idea if the Cimarron you are looking at has the older style firing pin or the new retractable one.
