>>94164Aside from early model Colts, you could fire .45ACP without the clips if you needed to, but to extract the cases you would then have to poke them out with a pencil or something.
A funny thing happens when these revolvers are surplused and sold on the commercial market later on, by the way.
A lot of people don't wanna bother with the half-moon (or full-moon) clips, finding them fiddly, so someone gets the idea of making a cartridge which duplicates the load of the .45ACP, but with a prominent rim, so you can drop these onto the extractor star of these revolvers, and it can lift them out without the aid of clips.
The .45 Auto Rim case can further be used for making .455 Webley ammunition, without having to use clips in those.
Many .455 Webley revolvers imported to the US had their cylinders "shaved" down so that .45ACP in clips could be used with them, but in hindsight this was a horrible idea, given that all factory loadings of this cartridge is a good few thousand PSI higher in pressure than .455 Webley
The only available .455 Webley ammo these days is from Fiocchi, and they make these cases with a small primer pocket and primer, which doesn't give enough of a oomph to set off all the powder, leading to a dirty and incomplete burn (so a bunch of fucking soot and unburnt powder in your revolver), and shitty ballistics, and the casings can't really be reloaded properly afterwards due to this situation. With .45 Auto Rim casings, you won't have this problem.
