Well I've looked at the currently made Ruger single actions and while they're no doubt stronger, I'm just not in love with the way they look. I actually really like the way the basic Blackhawk functions, but it's a little too modern for me. I wonder if a gunsmith could "old-westify" it with an under barrel web...
Howdy
Spend enough money, and you can probably accomplish just about anything.
If you are looking for the 'streamlined' Remington look, with the web under the barrel, you are talking about the Remington Model 1875.
Uberti makes a pretty good replica of these. The only real difference from the originals is the way the cylinder pin is removed. They call the 7 1/2" barrelled version the 'Outlaw'. Chambered for 45 Colt, available Nickel Plated or Blued and 'case hardened'. Their 'Frontier' model has a 5 1/2" barrel, blued and 'case hardened', 45 Colt. Their 1890 Single Action 'Police' is a pretty good replica of the Remington Model 1890. These had the web under the barrel cut down. The reason it is called 'Police' is because these were issued to some of the Indian Police on some of the reservations.

The web under the barrel of the 1875 Remington really did not add much strength to the gun, it was mostly a stylized nod to the appearance of the loading lever on the 1858 New Model Army Remington Cap & Ball revolvers. The web was attached to the underside of the barrel with one screw, and there was a pin pressed into the front of the frame that fit into a hole at the rear of the web.
On the 1890 Model the web had been cut down.
The pin pressed into the frame is visible poking slightly through its hole in the web on the underside of the 1890 Model.
This is my old EuroArms Remmie with its R&D conversion cylinder that allows it to fire 45 Colt ammunition. You can see how the shape of the loading lever has been mimicked by the Model 1875 Remington.
Regarding removing cylinders, there is no need to do so with a cartridge revolver. Most of them have a loading gate on the right side to remove empties and reload with live ammo.
The 'Conversion' revolvers are a bit different. Some of them use a loading gate, some, like my old Remmie, do not. But it is so quick and simple to remove the cylinder on the 1858 Remington that it really does not matter that there is no loading gate.
I lower the loading lever, pull the cylinder pin forward, and pop out the cylinder. Takes about ten seconds. Reload, and reverse the process. About another ten seconds to put the cylinder back in. This actually may be quicker than reloading a Colt, where you have to eject the empties, then reload, one chamber at a time. I'll have to try some time to see which is quicker.
It should be noted that the grip shape of the Remington Models 1875 and 1890 are a bit different than the grip shape of a Colt. The grip of the Remingtons extends back a bit further, providing a bit more space for the index finger behind the trigger guard.
