1911's always felt good to me for rapid fire - no need for sights at 25 yards or so, at least on the "metal" man.

I am reminded of a shoot many years ago, an IPSC match, through the bush on a trail. Had to take the targets as you found them, could only take one step back - standard IPSC target of 1976.
Jay Right, an RCMP "competition" PPC shooter chose to use his wife's 1911 .45, Bomor sighted 1911 - standard WW hardball load.
He won the match. One of the match coordinators noted, "don't know how you major'd all of the targets - I adjusted your rear sight a good 10 clicks left windage. Jay just smiled and said "who uses the sights?"
