Fake guns usually look like fake guns.
Real guns nowadays look like fake guns. It's a byproduct of the firearms industry switching to primarily polymer -- especially matte polymer -- construction for frames, grips, buttstocks, barrel shrouds, optics -- basically, any component that isn't related to trigger assemblies, chambers, or barrels that need to be made of metal, to withstand the internal stresses and pressures of firing a round.
That applies even to -- hell,
especially to -- wood grain-finish polymer.
Blame the actor/crew, not the gun.
I'm blaming
producers and
accountants. The pricks who'll spend hundreds of millions on dumbfuck effects and marketing, but won't greenlight ten to twenty thousand for conversion kits already in studio/armorer stock.
Nothing -- absolutely nothing whatsoever -- would have to be "created", as training kits I described earlier do not just exist, but are commercially-available to civilians and not just LEO/military. I could buy one,
today, for my home defense/EDC and it costs
maybe three to five hundred -- about half what the damn pistol cost in the first place -- depending on manufacturer, style, make, and model. All they are, are replacement slides and barrel assemblies,
maybe trigger assemblies and custom magazines for some, and most I've ever seen or heard of actually block the chamber to prevent live rounds from entering it.
Depending on aforementioned style, make, and model, there's zero aesthetic difference at all, except for safety coloration, and it would be trivially cheap for film industry armorers -- who have to hold FFL's and state entertainment firearms licenses -- to overcome.
And the kicker is it would likely cost studios
less in the long run to switch, thanks to lower insurance premiums for not having firearms capable of firing live rounds on sets.
