What firearm to do regret purchasing?

Grendel P12. Worst gun I ever owned. Changing the inherently weak clockwork hammer spring next to impossible. Once done and gone.

A glock. Picked one up in the early days, to see what the fuss was about. What an under engineered POS. Sold it when they were having OOB kabooms.

Went back to properly designed handguns with hammers and solid triggers.
