Not really! You list the common misconceptions and myths about the revolvers vs semi-autos argument.
You never had a revolver jam? That's likely because you didn't fire a lot of rounds through it. If you did, you would have run into issues. When a revolver jams, it is typically not fixable in a fight. When a semi-auto jams, it can be easily fixed and put back to work.
By the way, I have now 20,000 rounds through my Glock 19 and I can count the number of malfunctions with a single hand. Most of them were ammunition-induced (training ammunition with hard primers). One was created by a stupid aftermarket modification that I did. Another one was caused by me not holding the gun right and interfering with the slide.
As for the price tag argument, that's nonsense. A good revolver costs more than a good semi-auto.
As for the H&K USP, it has an outdated design, it is overpriced, and you get the bad HK customer service. The P2000 is the newer design that is based on the USP, by the way. The VP9 would be the right HK choice, if any.
