HK USP 9mm. Very reliable, very shootable.
Very reliable, yes. Shootable, sure. But definitely not more so, especially on the issue of shootability.
Give someone a properly built 1911/2011, and they'll outshoot themselves over just about any other gun they've shot, especially one they've never shot. And that just accelerates once they have time on the gun. If that wasn't the case, USPs would dominate competition shooting. It really is the only data point you need to gauge the "shootability" of a gun vs 1911s or 2011s - if there was any shootability edge to be had, competitors would be using them en masse.
BTW, it's worth defining "shootability" - it's not just about how easy a gun shoots for you, especially relaxed and at the range. And it's definitely not just how good it feels in the hand. It's something of a combo of how fast you can draw and fire it for first-round precision under duress, how well you can manage recoil with it, how fast you get subsequent rounds downrange on it, and comprehensively just how fast, accurate, and precise you get all those rounds grouped together on target.
On reliability, USPs score a lot higher for me than most other guns, and until the recent era I would have scored them far more reliable than 1911s. But modern-era 1911/2011s built on today's precision CNC machines in the last decade or so, especially the guns with proper low-friction coatings, are absolutely
excellent in terms of both reliability and durability. There's definitely quality differences by company, but properly built ones are phenomenal.
As reference, I have a Staccato C I put 5000+ rounds on in the last 6 months, without cleaning, while only re-lubing once with a lightweight grease at the 2500rd mark - it has had literally zero malfunctions that weren't ammo related. Thus far, if it threw a malfunction tomorrow, that's about twice the reliability of the most reliable guns I've ever shot before. And I have a lot of time on USPs from the 1990s, along with Sigs especially, and a few others. They're great guns, but they're just not same-same, especially on shootability.
BTW, I'm not saying USPs are bad or anything - this comment is addressing your response to saying the USP is more reliable and shootable than a 1911/2011 specifically. But I'd have no problems at all carrying a USP into bear country.
