Onmilo,I have owned my pair of .44 Colt Open Tops since they first came on the market.
These revolvers shoot both modern .44 Colt and .44 Russian cartridges equally as well.
They are good shooting revolvers but you may notice the spare springs I have in the case.
This is the only real fault I have had with the guns is the springs keep breaking.
Cylinderbolt/trigger spring, ejector spring, and that damned gate spring are the worst offenders.
I finally gave up on the standard flat bolt/trigger springs and installed Cylinder & Slide round wire replacements and they have yet to break again.
About those gate springs,,,
Has nothing to do with the rimfire issue. I'm aware of that. YOU did not make the distinction between it being offered as a candidate and actually being tested, neither does the book. Nor has anything else I've ever read. Including "US Martial Pistols & Revolvers" by Arcadi Gluckman. You simply acted as if you had a nugget in your pocket you did not want to share. Lovely argument over semantics, much obliged. Yes, I always have reading to do, condecension duly noted.The Open top was submitted as a candidate firearm but rejected for the .44 rimfire cartridge it chambered.
Because the .44Colt was simply a means to an end. It was just the largest cartridge that would physically fit into the 1860/Open Top platform, while still accomodating a heeled bullet large enough to obturate the percussion bore. The Model P was designed from the ground up with one purpose in mind, to get the military contract which demanded a solid frame and .45 caliber centerfire cartridge.Why did Colt basically drop the .44 Colt central and rimfire cartridges after the introduction of the Model P?
Because .44 rimfire ammunition was in great supply.Why did Colt make the 1872 revolver in a proprietary .44 Rimfire cartridge?
They did produce the Single Action Army in .44 Henry Flat rimfire in very limited quantities, why not the other two cartridges.
