the uberti is not good for an afternoon of heavy loads.
Howdy
That is incorrect.
Uberti revolvers are perfectly fine with ammunition that is loaded to SAAMI standards. Let's not forget that the 357 Magnum cartridge was first chambered in the Colt Single Action Army in 1935, shortly after its invention by Smith and Wesson. The cylinder for an Uberti or Colt has an outside diameter designed for the 45 Colt cartridge. So boring 357 diameter chambers leaves more metal between the chambers than with a 45 Colt. Current SAAMI maximum pressure for 357 Magnum is 35,000 psi, if memory serves. A Colt, or an Uberti chambered for 357 Magnum will hold up just fine with a steady diet of factory 357 Magnum loads. However because the revolver is relatively light recoil may be uncomfortable.
Yes, it is often said that Rugers are built like tanks. Standard Ruger Blackhawks are built on a larger frame than a Colt or an Uberti, which means the cylinder is even larger in diameter than a Colt or an Uberti. So boring .357 chambers in the Ruger cylinder will leave even more metal between chambers than with a Colt or Uberti. Also, Rugers incorporate a transfer bar, so they are completely safe to fully load with six rounds. The most recent Ubertis have a retracting firing pin in the hammer which should make them safe to carry fully loaded with six rounds. Not true with an older Uberti or a Colt, they must always be loaded with five rounds and an empty chamber under the hammer for safety's sake.
The other thing is just like a Colt Ubertis still use leaf springs, particularly for the split spring that controls the bolt and the trigger. It is not unknown for this spring to break, it has happened to me.
Ruger went to coil springs many years ago, even before they brought out the current transfer bar models in the 1970s. Coil springs are almost indestructible and almost never break. That is why Ruger went to them.
So you pays your money, you takes your choice.
If you want a revolver very similar to the old Colts, an Uberti is fine. If you want something a little bit heftier, go with the Ruger.
If you want adjustable sights, go with the Ruger Blackhawk.
If you want fixed sights, either the Ruger New Vaquero or the Uberti is the ticket.
