Many choices these days.
Steel frame vs. aluminum. Full size (5") vs. Commander (4" or 4.25"). 9mm vs 45 vs others. Series 70 or 80 triggers.
Many brands now offer optical sight compatible models.
Shorter and lighter is easier to carry, steel and full size is more pleasant to shoot at the range.
I have moved to 9mm with subsonic ammo. 9mm is cheaper than 45 and has less recoil. Like Bill Wilson, I prefer the absence of the high velocity crack and have gone to subsonic ammo. I hit 80 this year and high round count days are more pleasant for me with this combination.
I still have some 1911s in 45 , but they get less use these days.
A host of good brands to choose from. Springfield Armory has a diverse line at good prices. My 1911 friends say they are good quality. Colt's QC is said to have been up and down over the past years. I do not know what CZ ownership has done for that. Kimber had some issues in the past, but many say they are better now. Tisas gets good reviews and are cheaper than many other brands. Dan Wesson 1911s are highly regarded. Like I started with: Many choices these days.
