holy crap thanks for posting this, I never knew mine was plastic.

The trigger for sure has a metal skeleton, so don't worry about it breaking. I think, but am not sure, that the safety has metal in it as well, I bet someone else will be along to say for sure. Regardless, I wouldn't worry about it. In fact, I don't. I have no problem with the plastic on my M9 and have never read or seen a report of one breaking. I googled it just now to see if this was a problem, and got no results.

Is this a case of hearing something about people having negative experiences with this part, or is it just fear of polymer parts on guns? If the former, please share as I will happily change my opinion with supporting evidence. If the latter, well to each their own I suppose, personally I find the fear of plastic parts on high end guns silly.

The trigger and safety lever body have a metal core, covered in polymer. The firing pin plunger, as well as the other springs and detents ride within the metal core...

You can not get a magnet to stick to them, but they have enough metal in the areas needed to ensure reliable function.

I actually like the polymer guide rod. It is not as easily bent or damaged as the older metal part. The polymer hammer cap is also very durable and doesn't get bent and shiney from use. The magazine catch still has metal inserts to hold the magazine.

I am guessing it is faster and easier for Beretta to mold polymer parts as opposed to machining them. The polymer doesn't rust either

One thing seems to be expected ...... that is, every product seems to get heavier as time goes on. The current reasons for handguns appear to be due to reshaping frames to have Picatinny rails, and adding extensions to magazines to increase mag capacaties from 15 to 18, 20, or 30 rounds. If changing components from metal to plastic or polymer for parts whose MTBF is not significantly impaired by the change, I have no reservations.

However, some things do appear, at a glance, to make a difference. I remember, in Basic Training in 1970, being shown how to hit the enemy soldier in the face/head with the butt of the rifle, ye olde "butt stroke", and thinking to myself that if I did the buttstroke with an M1903A3, Garand, or M-14, the enemy's face/head would not survive, but my rifle butt would, whereas I was not so certain that my "Plastic Fantastic", my M-16, would. As things turned out, I never got an opportunity to find out for sure.

People felt the same way when stamped steel parts were used to replace milled steel gun parts 60 years ago. Change with the times.

Only the left side lever is plastic. Safety and right side lever is all steel.
I replaced all plastic junk with steel parts.

First to go was a "self-lubricating" plastic guide rod.
This thing did not withstand propane heat.

I'm not a fan of plastic parts or that cheap, peeling, chipping paint called Bruniton.

I purchased Beretta parts from them. They're good to go.
The parts are new, beautiful.
I compared them to parts from 1985 Italian 92 F, which by the way is all steel.
I cannot tell the difference in workmanship or the finish.

Whether these are surplus, I don't know, so I take his word for it.

Nope. I dont leave one in the chamber tho. Just loaded mag.

Thanks for the link richard257.
