The third photo, showing the ejector in action, and demonstrating .45ACP casings being ejected just fine. Some people do a double take upon hearing about this kind of gun, forgetting that moon clips and half moon clips are only necessary if a revolver extracts by lifting under the rim of a cartridge, aside from certain more complex styles of extractor stars which grab onto the groove of rimless cartridges (these designs can be somewhat delicate and brittle, as I hear). As it's a literal rod poking the bottom of the case, it shouldn't ever struggle.
You also see quite a lot of fingerprints smudged all over the cylinder, from when he swapped it from the regular .45 Colt cylinder. With traditional high end blued finishes, you'll want to maybe carefully wipe a gun a little bit after handling it a lot, if you're very concerned about it looking clean and pristine, as the oils secreted by your skin can actually wear on this type of finish (this will depend on you as a person, some people's skin oils can be harsher on bluing than others).
Ruger on the other hand isn't exactly a high end custom shop or anything, and they do their finishes at a more typical consumer grade, which is fine, but also not deluxe enough that you'll feel the need to worry.
Also having fucking syringes jammed into your mouth for anesthetics hurts like a cunt, I'll never get used to that.
