Gen4 glock 20 or witness polymer?

[10mmfan]

Former gen3 20sf owner here I sold the gun in hopes of buying a gen4 but bought the 10mm ria instead. I miss the glock butit looks like it's a problem child would I be better off with a witness polymer?

Stick with a Glock in Gen 3 imho.

You have a 1911...Get the Glock.

Gen4 G20's are proving to be tempermental with mid to high power loadings, and so far, Glock is giving no indication they view it as a problem.  Had I had to pick again, I'd have got a Gen3 or Gen3SF, not the Gen4.  IF they fix the Gen4, then I'd rather have the Gen4.  But they haven't done that yet...
