I have never owned a 45 ACP 1911, so I was wondering about the Springfield PX9149LP Loaded Champion Lightweight OD Green / Black Armory Kote: Good choice.
Are Springfields made in Brazil and assembled in the U.S.A.? I want to buy 100% American, so maybe Springfield isn't a good choice. I also want stellar customer service. Actually, who cares? Whether the metals are cast and machined in the US or cast and machined elsewhere under Springfield quality control standards you get the same pistol. The metals used are probably exported from the US to Brazil and processed under US specs. Stellar customer service - what, a blonde in a two piece that says 'yes' to your every question? Most factories I have dealt with give good service with a good turn-around time but just to be curious, what problems do oyou think you would encounter that would require service you could not perform yourself??
Is the fully supported ramp barrel needed to protect the lightweight alloy frame?: No.
I want to shoot 185 hollow points, so is the fully supported ramp barrel for feeding? Now what on earth would you want to do that for - target work maybe with the 185 gn wadcutters I can personally agree with but for defensive purposes, why bother? No, a fully supported ramp barrel is not necessary for reliable feeding of hollowpoints or soft nose slugs, imho.
I have also considered Kimber and Colts, but I don't see if they have fully supported ramp barrels. Kimber is a excellent choice, Colt can go whizz up a rope. Supported barrels are not a issue for regular 1911A1 45 acp use.
Supported barrels are useful though, they add strength to the frame (I believe) but more importantly add reliability in cycling and strength to the chamber area for the use of heavy, high performance wide or open face bullets that might normally cause problems in cycling. Truely, unless you are planning to use the pistol for competition I do not feel a fully supported barrel is necessary.
