Double action revolvers ... metallic cartridges ... center fire ammunition ... smokeless powder ... aluminum frames!?!
I imagine a few firearms innovations were met with a bit of initial skepticism and mistrust over the years.
Granted, I've always appreciated a well-crafted steel handgun with wood grips. I even traded off a Colt lightweight Commander for one of the then-new Combat Commanders ... for concern over the durability of the aluminum frame. Wish I'd kept it, of course.
I came a bit late to accepting polymer-framed pistols. I liked the P9S chambered in .45 ACP which I carried for a while, but didn't particularly care for the Glock when it was first released. The grip angle, heft, balance and trigger were 'odd' compared to the steel & aluminum-framed pistols I favored and carried.
Fast forward a number of years and I find I own a couple of Glocks, a couple of Walther-framed SW99's and have a M&P45 on order.
I've fired thousands and thousands of rounds through polymer-framed guns in the several years I've owned personal examples and carried an issued SW99 chambered in .40 S&W for a few years.
I've been through 7 armorer classes for 4 different polymer-framed pistols.
Granted, if I were unlucky enough to experience an over-pressure event I'd prefer to have a metal-framed pistol in my hand.
Polymer can be chipped, cracked and broken a bit easier than steel or aluminum in some unintended impact situations ... but it also withstands some stresses commonly expected to occur in the normal operation of a pistol better than some metal frames, too.
Certainly lighter and easier to carry around all day.
I think the major manufacturers have done rather well with recognizing and properly utilizing the inherent advantages and strengths of polymer frames in many of the high quality pistols available on the market.
It's less expensive to produce a pistol which uses a molded polymer frame, as well.
Owning 5 polymer-framed pistols might be 'enough' for me ... and having only 1 polymer-framed .45 pistol among the 9 of them I'll shortly own might be 'enough' when it comes to plastic .45's, too.
When all is said and done I look at polymer-framed pistols as functional, easy to maintain, serviceable tools rather than 'works of art'.
I reserve that status for nicely done single action revolvers. Everything else is just a handgun.
