I have three revolvers that chamber cartridges for automatics. A Colt Model 1917, a S&W Model 1917, and a S&W Model 625 of 1988. All three are chambered in .45 ACP and a hoot to shoot. I enjoy them and like the ability to shoot .45 ACP, .45 Auto Rim, and .45 GAP out of them. Yeah, you read that right. .45 GAP.....
The .45 Auto Rim is a .45 ACP cartridge with a rimmed case. So no moon clips are needed. Additionally, the case web is thicker so you can load .45 Auto Rim a bit spicier than .45 ACP. The .45 GAP is an added bonus because I get it for cheap and having 200gr Speer Gold Dot for less than five bucks a box ain't bad.
I'd like a revolver in 10mm and .40 S&W since I have a pile of both. I have my .41 Magnums, .44 Magnums, .45 Colts, .357 Magnums, and .38 Specials too. But I own guns because they put a smile on my face. I don't need a "reason" to justify them. I don't need to buy them because I have to have a "HD Gun" or a "Trunk/Truck Gun" or a "SHTF/Boogaloo Gun".
I like the novelty of some designs just because of the novelty. So having a moonclip fed revolver in 10mm and .40 S&W would be nice. The Ruger GP100 Match has issues with .40 S&W and the current generation S&W Model 610 has the damn lock. So it would be nice if Colt released a gun similar to a the 610, but without the damn lock.
