As far as trends, I don't know why they have to make all the plastic guns so UGLY. Not everybody wants squared off fronts and rails. How about a gracefully curved, tapered oval trigger guard? Think PPK, but with all the goodness of what plastic brings to the table.
Same with small guns. Why the tilting barrel down to 9mm, then the fixed barrel at .380 and lower (I know, not always)?
How about Beretta come out with their Bobcat and Tomcat in plastic? (Or are they already?)
How about a plastic PPK? You'll get the reduced cost, light weight, etc.
Just trying to think of all the modern materials and processes, with the great designs and thinking from the past.
Again, why such UGLY PLASTIC GUNS, especially if it costs no more to make them nicer looking? Round those edges, drop the rails, smooth it out. Make it easy to draw, and lighter to carry.
