Maybe Colt will take the tooling for the 2000 out of mothballs.
People are all screaming for .45... Just wait until they see the bill for a massive overhaul to a new pistol, combined with costs for training with the new round... Or old round, however you want to see it.
9mm is just as effective and ineffective as .45. You can unload some hi-cap Para into a guy and if you don't hit them in the engine room or bridge, they are going to be JUST as effective as someone shot in similar fashion as a 9mm. This is purely a training and maintenance issue, not a caliber issue. Our troops training regimen is laughable at best. We have become a bloated bureaucracy and those not doing combat duty are given a pistol. They need a carbine or PDW style weapon: Give them rifle power in a compact package (as their task, driver, medic, etc... requires compact, not power... give them both).
For every ONE person I've heard pitch a fit about the M9, I've heard 10 that have either had no issue or actually had an M9 save their bacon. Then again, the same folks that pitch a fit about the M9 seemed to pitch a fit about anything else the military gave them. "Oh man, what I would have done if I had an M14!!" Well, did they give you one, have you fired one? "No." Stop depending so much on hardware, start looking at the software.
Instead of some new pistol or a larger, more expensive caliber, how about actually spending the money (that our nation DOESN'T have) into training? Oh, yeah, that would be too easy. Just like anything else related to shooting: We want it to be hardware or accessory based, not software (us) based. We want whiz bang, not actual training. We want lasers, we don't want to have to sit through a class and shoot to train. We want idiot crap on our guns, rather than learning to shoot. We want to rely on a caliber or bullet type, not train in shooting past 15 yards.
I am a big FN fan and the 5.7 x 28 has it's pluses, but over penetration may be a problem. I am also a big Colt fan and the 10 mm has it's pluses. I think it may come down to these two rounds. For me, the hard hitting 10 mm would get my Cartridge Vote and Colt would get my Manufacture Vote.
10 will win over the 5.7 by nose. That won't keep me from wanting a 5.7 FN. :>)
It won't be a 1911. Found this at Wikipedia. Modular Handgun System - Wikipedia, the free encyclopedia
They really want a lot. 90% chance of hitting a 4" circle at 50m by whom?
I'll also guess that it ends up staying 9mm. As the article states
