No offense, that's not a question, that's a statement based on a lack of understanding about what you are talking about.
To elaborate:
The Bren Ten was a great design, based as it was on a scaled-up CZ-75. Having actually SHOT the gun, and not just listend to gun-store B.S., the Bren Ten exhibits several notable qualities. The most interesting one is its apparent lack of recoil, even when shooting hot loads. It is a very soft-shooter with little muzzle flip compared to even a ported Glock 20C or bull-barreled SV widebody. Aside from the noise and blast, it feels like shooting hardball from a .45. The ergonomics are also outstanding, which makes sense since it borrows so heavily from the CZ-75. They feed almost anything reliably, and can be extremely reliable and durable. My friend has a Bren Ten that has untold tens of thousands of rounds through it with no ill effects.
HOWEVER, there is no denying that Doranus & Dixon were incompetent as hell, QC varied from brilliant to flaky depending on the phase of the moon (extractors being a notable problem), and for some reason supplying
magazines was beyond their capacity (no pun intended
)... they are famous for being delivered in some cases without any magazines at all! So the company rolled over and died.
As for the cartridge, the notion that it is "all hype" is a total joke. The ballistics speak for themselves. It gives you more power and much more versatility than .40 S&W, .45 ACP +P or .357 Sig. Indeed, for weight-at-speed it can outclass .357 Magnum with a fatter bullet. Some hype!
EDITED TO ADD: It figures Tamara would beat me to the punch.
