I'd be buying a lot more revolvers if the revolvers I want were being made.
Non-fluted cylinders, slab sided barrels, unnecessary machining on the ejector rod housing, accessory rails, porting, JM initials on the side (if anyone's initials are going there it will be mine), lack of the barrel lengths I want, etc.
Some examples:
Stainless version of the 27, with traditional features such as the (example) 27-2 had, including checkering on the top strap and barrel rib. Five, six or six and a half inch barrels.
Model 25 family. Can't get a 3" 625. Nor a 5". And the 4" either has someone else's initials on it, or has a non-traditional barrel. The 325 would be awesome with a 3" full underlug barrel without slab sides.
Model 69. It's a no brainer this gun should be made in 3". I can't even have the barrel cut to 3" and the sight moved because it is the shrouded barrel version.
There would be two black tire marks out of my driveway to get a blued clone of a 19 or a stainless clone of a 66 with an 8-3/8" barrel chambered for .327 Federal Magnum. This would be a very flexible revolver for small game, varmints, pest control, and the smaller predators, even coyotes at handgun ranges. The long barrel is needed for sight radius for accuracy. A full underlug is not needed and would be too muzzle heavy.
I'd also like to see a twin of the above in 17 HMR. A full underlug is not needed with this cartridge, but the 8-3/8" barrel would be nice. (I've had Jets, and both of these would be more useful to me than any Jet was.)
I could go on and on with other examples, but the point is I want traditional looking guns, without gimmicks, and in useful calibers and barrel lengths. Combine that with S&W not offering metal frame double action autos anymore and that's why I'm out running amok buying SIG Sauers.
