The 1911 is not a platform I recommend to a new gun owner as a carry piece.
The 1911 was the service duty pistol in the us military for a long time and when properly tuned and cared for is very reliable.
The XD line from Springfield is the Prvi Hrvatski Pištolj or First Croatian Pistol.
It is actually the HS2000.
The HS2000 was adopted by the Croatian military and law enforcement as a standard issue sidearm and continues to fill that role.
A very reliable platform, internally almost Identical to the Glock and it has a grip safely.
Smith & Wesson's M&P line is also proven and in use by several Law enforcement agencies.
Almost every carry piece I have seen mentioned here I would not hesitate to utilize.
As with any piece of equipment it has to be tested, preferably with the rounds you will be using,
and it needs to be maintained. It is a mechanical piece and can fail, it is not end all be all just a tool in your arsenal.
