The CZ 75B Omega. It perfectly accepts the 40SW Mags, which you can fit 13 rounds of 9 mm into. About 3000 rounds in and hasn't jammed/failed yet.
I'm an advocate for the CZ 75/85 platform. Although, I have never shot the "Omega", I have read about the internals being different than the original 75 design, and the triggers being not so nice. It is also interesting to note that there are so many copies and clones of the CZ, and most are so true to the original that most internals are interchangeable between these clones. Norinco, Sphinx, Tanfoglio, and the Jericho come to mind; I believe there are others. Before committing to the CZ I decided to by a lower priced clone to try, and after doing a lot of research, I bought a Norinco NZ85B. At $400 new, it was not as "cheap" as most Norks, but it was about half the price of a new CZ. Since that time I have shot a couple different Sphinxs, a few different CZs (not the omega), and I own a Jericho in .40.
Two problems with the Nork; the stock grips suck; but I got a set of CZ overmolded rubber grips (the basic stock from the factory ones) and they fit right on; it now feels exactly like the CZ.
The other problem is it shoots so well, is so easy to shoot accurately, and is 100% reliable, I can't justify changing to a CZ at this point.
You are correct about the .40 S & W mags; I have tried both the stock mags that came with my Jericho, and the aftermarket Mec Gar Mag I bought for it; I actually get 14 9mm in each, and the do feed flawlessly.
BTW, the Jericho feeds .40s regardless of bullet type flawlessly as well.
Why not Glock? While they are reliable, and they do shoot amazingly accurately, they are (IMO) ugly, the grips are uncomfortable, the grip angle is uncomfortable, and the point of balance is unnatural for me. No question, they do work. Why are they so popular... Well, law enforcement and military buy lots of them because they are cheap to buy, because they are cheap to build, so they have become ubiquitous. There are lots of Toyota Corollas on the road for the same reason, cheap and they work; but they are not a Lexus.
