IMHO the main reason the 1911 is so popular today and has been around so long is because of two things; 45acp caliber and the fact that it is SAO.
That said there are other pistols out there that have been chambered in 45acp and are either SAO like the 1911 or can be carried cocked and locked as well as as in DA mode with the hammer down like the CZ75 type pistols. Of all these others which pistol chambered in 445acp is the best that is either SAO or can be carried locked and cocked and is not a 1911 clone?
