No.
I only own one, and the only reason I have it, is I kept it after testing and evaluating it.
It fits a niche for me, and therefore I only recommend it/ other poly guns to fit a niche.
I prefer wood and blue. and this talk of blue being harder to keep up and rusts, just makes me snicker, look at how many guns made of wood and blue, are still around?
Ease of maintaining comes up, well then , if folks really did inspect and maintain properly, they would not have problems.
How many folks bought a Stainless gun "because it won't rust" and we see post all the time "My stainless gun has rust!"
Stain-less means "stains" + "less" - it will rust, just less prone to do so.
It is still the responsibility of the owner to properly inspect and maintain.
Poly :
These will rust. Yep, sure will. rust will cause steel springs, and other internals to weaken and break too.
Now that o-l-d revolver, or semi auto can be taken down, and I do mean "down" and some are easier to do so than others.
Oh there may be some flecks of run, worn finish, bluing gone, this stuff on the exterior is not what keeps one alive, it is the internals that keeps one alive.
I have heard and felt the "click" of a busted internal part, and it is not that easy to get all the way into a Poly gun to fix it.
The poly only like to have pins removed so many times, before problems start.
Metal guns will wear too, just some by design allows one to get to internals, and this wear problem is easier to fix.
One still has to inspect and maintain - never a good idea to rely on Marketing, Hype, and Buzzwords.
Just my thoughts...
