Just thought I'd throw this out for discussion as to whether or not it's a good idea, but based on some things I see in the firearm industry, it might be.
The whole moon clip concept, as we know, was a WWI necessity based on dealing with a shortage of 1911 pistols. While some consider moon clips to be the bee's knees, others (myself included) regard them as a total PITA, hence the development of the .45 Auto Rim cartridge.
Some points for this discussion:
1. It is rapidly becoming a 9x19mm world out there. We've seen some 9mm revolvers come along - mostly in comp guns. Some cops will still buy a .38 revolver as a backup, but many of them are drawn to the concept of "free ammo" that their agency provides, so the concept of a moon-clippable 9mm snubby revolver may make a comeback . . . at least if the mini-9mm autos don't sweep the idea away entirely. An Auto Rim version of the round might not be far behind. This overall concept would allow for a revisitation of the heavy .38 S&W concept that was utilized in the mid-20th century. A shorter-than-.38 frame and cylinder length might be a reasonable thing to insert into production. Long enough to allow for up to 200 grain bullets, but a shorter overall gun that has been possible with the .38 Special COAL.
1-A. An opposite direction we could go from the above would be to introduce a "9mm Auto Rim Long" to the party, which would basically come in at a .38 Special or .357 Magnum overall length and be rated at .357 mag-level pressures. This would allow us to keep the .357 performance envelope with the bullet diameter of the 9x19. The same gun could then shoot this round, as well as the 9mmAR or the standard 9x19 moon-clipped.
2. We already have some moon-clippable 10mm revolvers out there, and an Auto-Rim brass option might make for an option to the .41 Mag. The same revolvers would be able to dispose of .40 S&W as well (which could also get the AR treatment). The owner would essentially have a very versatile platform for running up to the 38-.40WCF performance range.
3. The .45ACP/Auto Rim revolver is a well-tested concept, but why not take it a little farther by putting the thick Auto Rim onto the .45 Colt case and standardize the guns on .451"-.452" bullets? This would give the user the "Special" option of the ACP length round for defense and the "Magnum" option of the modified Colt case for hunting.
4. That which can be done in revolvers, can also be done in carbines - lever action and otherwise.
5. Single action / loading gate guns chambered for the above would still require a separate cylinder to run the rimless rounds in addition to the longer "magnum" versions, but the versatility would still be there.
The old revolver cartridges will stay with us, but I see this as a possible way for folks to keep the same performance envelopes with a smaller collection of dies and loading components.
So. . .setting aside what you already own and most of us being old farts unwilling to change, worthy of nagging the industry?
