I've had a 3 1/2" Uberti Thunderer in .45 Colt for several years, and it is one of my favorite handguns. I think the company called it the "New Thunderer" when it first came out in the 1990s, about the time I bought mine. I also held out for the checkered grips. The Birds head style grip, combined with the "ledge" as others have mentioned, plus the checkering all help to keep recoil down.
I replaced the base pin with a Belt Mountain pin, and had a trusted local gunsmith do an action job that at the time cost $45. I ordered a custom El Paso Saddlery Cross Draw holster for it as well, something I probably could not afford to do today. The revolver shoots 255 grain Oregon Trail SWC bullets behind 7 grains of Unique into wonderful little groups.
One day a few years back I landed belly down in a cold, cold stream near the Continental Divide while hiking way up high in the mountains with my wife west of Leadville, Colorado while wearing the revolver and holster.
When we got back to the jeep the only thing useful I could find was a can of WD-40. I took the grips off and sprayed half the bottle into the inside of the gun and then wrapped the gun up in some Wd-40 treated newspapers. I wrapped old dry socks into and around the hoslter.
When we got home the next day and I was able to take everything apart, there was just a few bits of rust remaining on the inside of the gun. The gun and holster cleaned up very well and are back in use.
I think you will enjoy just such a gun.
