I should also mention that I don’t own any product from either company. Colt is overpriced substandard junk and HKs are just plain overpriced.
I've owned several Colt handguns over the years (sold them all). I've never owned an HK - always felt like there were alternatives available, that were as good or better than HK products, and a lot more affordable (for example, I've owned several FALs).
You mentioned the lack of Colt polymer handguns; seems like some of the All American 2000s had polymer frames. Maybe if Colt hadn't messed with the original Knight-Stoner design (which reportedly had a better trigger, wasn't "butt ugly", etc.), and had maintained decent QC, it would have been a successful design...
