I can't speak to any of the others but I once owned an FEG , it went away.

Just for the record - why?
Since FN is the original maker, that would be my first choice.
1. Changing magazines changed the trigger , it might have an acceptable trigger with one magazine and a terrible trigger with the next magazine.
2. Some factory ammo was too long to work in the factory magazine.
3. I despise a magazine disconnect safety on a handgun.
