Consider the 1911 for what it is and what it was. Though I've been fortunate with what I own and carry, a real review of what a user expects a 1911 to do is in order.
I found excellent information about the 1911 on 10-8 Performance. They have listed many discussion points about using a 1911 for daily carrying and especially as a duty weapon.

A key consideration is that the law enforcement officer and the military service member typically has a dedicated armorer support.
There's much to think about before purchasing a 1911. There's enough to really look to another pistol. Just consider how much training goes into the failure drills for a 1911. Yes, I've carried a 1911 on a regular basis, but I've updated my daily carry to something developed in the last decade or so.
I've looked at several recent designs and weighed the various pros and cons of which one (or several for family) to purchase.
