back to the original pressure question...
my colt double Eagle 40 was a 1911 frame, and built like a brick outhouse. I've read 40 pressure can get up to 40,000 psi, but most saw it is in the 32K range.
The same gun was used to make a 45, a 9mm, a 38 super, and a 10mm.
I'd LOVE to have a Double Eagle in 10mm in the Commander size, or even better, the Officer's, but I doubt it was made that small.
