I heard the plastic guide rod is a weakness. I contacted my favorite parts guy and he said he has none. He also does not like the third gen Smith autos as he says they are all problematic.
My concern is the small parts. I would presume Wolff has springs.
I know a gunsmith who will make parts for me but I would have to give him the deed to my house.
Just the same, I like this gun and still want one. I see there are some for sale on the internet. I can pay up to $500 for one, and I have three Glocks and that's enough. Thank you all for your help.
