Cold hard facts for pliable, stretchy, soft plast.. sorry polymers.
Yes, polymer framed pistols are lighter, easier to carry. But also much harder to shoot than steel framed equivalents. Who says so? All the inexperienced first time shooters that come to the range, and after they try the g19/17 and the 5906, the targets tell the tale. By far bigger difference between g21 and 4506 or 1911s. And these people's opinion matters twice as much, because they all come hyped to shoot the Holywood's favorite, and hadn't it been for the metal guns, they would go away disappointed. Heavier handguns tame recoil. Period.
Polymer strength. Yes, we can all attest to how far polymers have improved over the past 2-3 decades. However, I am still waiting for successful polymer barrels/chambers, polymer revolver cylinders, polymer springs (flat and coil), and of course polymer slides, with all these benefits that polymer has.(The 1958 Winchester shotgun barrel does not count. It had a metallic liner). And my all time favorite devastating anti polymer example, none would benefit more from weight reduction than the navy or the artillery. So, where are those plastic naval guns or howitzers? Thank you!
Also, is there a chance polymer frames may get wasted to household chemicals like gasoline and/or brake fluid?? I don't know. Steel, aluminum, wood will not, and we all know that.
Longevity. The "Iceman" was discovered in the Alps, at the place he fell 3000 years ago. His wooden bows and leather bags and quiver where found next to him. Actually, the documentary said that the scientists managed to recondition the leather pouches and to open them to find their contents!!! On the other hand, on my field boots the first thing that says goodbye, has never been the leather upper, but the rubber sole. And not just in mine. (I am not talking natural tread wear, rather the mid sole usually cracking and falling apart.) Also, in the various cars I have ever owned, the first parts to break, go loose, crack, stretch, fall, discolor, have always been (you guessed it) the nonmetallic ones.
Cheaper to produce. Hell yes!! I recall from back in the nineties, when S&W's treacherous redcoat management decided to copy Glock and produce the Sigma. The litigation ended with S&W paying royalties to Glock, 17 dollars American for each Sigma they sold. This was supposedly the cost for a Glock, (or a Sigma apparently). Therefore, when a metallic framed pistol, a wonder of machining, can be had for 500 dollars, a mold injected polymer framed pistol should be selling for a 150 dollars. Not one dollar more.
Conclusion. Polymer has two advantages only. Low cost, and low weight. Since this cost reduction is not reflected in the price, thanx, but no thanx. And truth be told, had it not been for cost, and cost alone, plastic would never fly. The only reason trash bags are plastic is just that. Cost. To those that claim plastic framed pistols are lighter, therefore easier to carry, absolutely correct. However, personally, I would rather carry a better pistol, (or if you wish a pistol I liked better) and suffer the more weight (and of course that is what I do) especially if I was armed for a living!!!. The ugly truth is though, most people i hear complain about the extra weight are people like me, who are already overweight them selves, yet they complain about the extra 10 ounces. And in my book that is a not valid point. Just my two cents friends!
