Why dont we see 9mm automatic? It is a far superior round

>>34338065
Because it doesn't exist beyond prototypes

>what is the desert eagle in 357 or 44 magnum

>>34338278
shooting rimmed revovler cartridges

>>34338278
Isn't the desert eagle really finicky? Probably not the best example.

>>34338065
Because it's a solution in search of a problem.

>>34338347

It is.

Tapered cases exist for a reason.

>>34338067
iirc the curve is to help feeding

>>34338347
LAR Grizzly is a better example.

There's a reason that even Colt didn't offer their repeating rifles in .45 Colt and instead chambered them for .44 WCF, and it's because straight-walled cartridges don't reliably extract.

.380, .40 S&W, .45 ACP, 10mm, .38 Super and probably several others all use straight walled cases, and all work wonderfully in semi automatic pistols. The problem isn't that 9mm Auto is any harder to extract than anything else. The problem is that it's entire marketing angle is "Exactly the same performance as, but not interchangeable with that thing that everyone on the planet already uses."

>>34338630
The only one of those that doesn't have a very slight taper is the .38 Super, and surprise surprise, no one uses it anymore.

it's the 45 GAP of 9mm's. Not even stuffing it in a Glock and calling it perfect can breathe life into it.

>>34338347
The DEagle's gas system demands you firmly grasp it and punishes those with poor form or little handlets by refusing to feed.

>>34338895
A lot of target shooters use it, there are many 1911s chambered in it

>>34338524
I thought it was because the bottleneck helped seal the chamber from powder fouling
