No sweat. My thinking is that to build a 9mm 1911, you have changed the following:
recoil impulse
cartridge length
cartridge diameter
cartridge is now tapered instead of straight
Given that 1911s are pretty mag sensitive, and that there are a ton of different mag manufacturers and only one has the spec to build a guaranteed functional one (Colt, and they periodically ignore the drawings) AND that set of drawings is for a gun firing an FMJ bullet that weighs almost twice as much as the one that goes in a 9mm 1911...
And as recently was discussed on PFC (and specifically in regards to 1911s as you likely recall but for the benefit of others anyway...) unless your gun sucks or is busted, it does the same thing on every shot. Slide goes back the same distance, hammer gets cocked to the same degree, barrel tilts the same amount, etc etc etc.
The magazine, on the other hand, changes on every shot. The amount of upward pressure changes. The amount of friction on the round being loaded changes. The angle of the round being presented to the chamber changes.
On top of that you have now taken a gun designed to run a straight walled cartridge one size, and stuck a tapered cartridge of different size in it. And are expecting it to cycle equally well the whole way through the mag.
It's not that nobody builds a working 9mm government - hey, Todd's gun got past 50,000 rounds right?
But in my opinion it's working at the edge of the envelope. And more importantly, the guys at Wilson Combat agree, and they're probably better at building working 9mm 1911s than anyone right now. And in fact I think the guys at Heirloom are thinking in a similar vein, although I don't remember now if they're building a 5" or a 4 1/4 for Todd.
