My point there is that the once racist-termed-but-not-in-this-case Saturday Night Specials, the cheap, poor quality revolvers made in the 1950's, 60's and 70's were zinc-framed. Just like Lorcin, Jennings, Raven, Davis, and now Cobra autos, which are crap (and perhaps the ultimate evolution of the SNS, considering they are the pistols most used in urban crime), the earlier revolvers were, well, crap and any company that produced a revolver with a zinc frame, even if the revolver weren't terribly bad (no zinc revolver is good), is keeping one foot in the dark side of the force.
Put it another way, the aforementioned Lorcins et al. are crap, which we all know (for this discussion, anything made by Haskel, Hi-Point, Beemiller, etc are ignored), are all single action, striker-fired, blow-back operated, zinc framed automatics. Now, if SIG or H&K, or Glock came out with a zinc-framed, single action, striker-fired blowback, they would be producing something in the same class as a Lorcin or Bryco. Now, arguably, a SIG made pistol of Lorcin design would be better made. Conversely, a 220 design made by Lorcin would be poorly made. Yet, if SIG were to make said zinc auto, they would be "Dancing with the devil" in that they would be making an auto of the same overall construction as the modern day SNS.
SIG would not think of making a zinc auto. They use aluminum alloys, which are much, much better than zinc, but also much more expensive to machine. There is just about no machining in a zinc auto, their frames, slides, grip serations, indeed most features are not machined but cast in that configuration already (which is why zinc autos are so cheap). Any company that did resort to a zinc-framed auto would already be admitting that they are willing to produce something in the same class as the SNS.
By the way, zinc has such a low melting point, you can melt it with a common blow torch. If you doubt me, take any modern penny, put it on a hunk of steel such as a vice, and apply heat. They melt quickly because they are mostly zinc. You could take a Jennings and try the same experiment, but a penny is cheaper than $45.
That Weihrauch is willing to produce a zinc-framed revolver, which is exactly what the old SNS was, then they are "Dancing with the devil" of the Saturday Night Special. They might not be in bed with him, the way RG, Rhome, (and even Weirarch was with some of their Arminius revolvers, many of which were indeed zinc SNS's) were, or Lorcin, Jennings, Davis, Ravin, Corbra, and the like were and are still today. Yet, they have their foot in that cauldron of zinc that they pour to make some revolvers.
As such, they dance, man they dance.
