I saw a post in the revolver question about the unnecessary empty case space in 38 special.
That prompts me to ask the question: Have there been any modern revolvers in calibers less than 38 where they have trimmed down the cylinder for efficiency? For example, Ruger has the LCR in 9mm I believe. Did they shorten the cylinder because they could, or keep it the same length as 38 special? A short cylinder would be significantly lighter and you'd get longer barrel length out the same form factor.
