I picked up a can of this a while ago.
I noticed it has a warning about using it on some plastics.
Was cleaning my Shield the other day and passed on using it on the plastic frame. I was going to spray out the frame parts with it.

Have you used this on a plastic gun frame?

I use GS only as a pressure rinse off after cleaning metal parts with Hoppe's or other cleaning solvents. I have a can that shows "synthetic safe" though I don't use it on polymer frames as you're asking about.

Thats the "old" kind. It is for metal only, the newer all purpose formula that Phil posted is OK for polymer.

Yes, I have used a LOT of both kinds, plus RED Brak Kl;een.

Non chlorinated brake cleaner for me. It's way cheaper at a discount auto parts place and is basically the same stuff.

Been using it for years on my Glock pistols with no problem at all . Polymer is not plastic

After 16 years in the plastics industry, I guarantee that polymer is plastic. It's just another word for it.
A Polymer is generally produced by combining a base (Plastic, petroleum derived component). with a catalyst for hardening/setting to shape. Epoxy is a type of polymer.

What's odd is the can says, "synthetic safe." That's so broad as to be meaningless. If it's safe on plastic, just say so.

I've used red Brakleen on my shield .40. For most pistols I remove laser guards or grips before using a spray.
