No Easy Answer
I thread like this could easily run to a thousand responses as most everybody knows most everything regarding the 1911. Just try us!
Anyway, do you plan to be a competition shooter or an informal target shooter? Will this be your self-defense gun in the nightstand?
As with the old standby US Army issue 1911, they sounded like an infants' rattle if you shook one but they were reliable. They provided reasonable combat accuracy but "accurizing" 1911s began on the GI issue guns.
If you're an informal shooter and the gun will reside in the nightstand, perhaps something in the $1000.00 range would be perfectly fine. No point in spending $3000.00 or so on a plinker.
I have an S&W 1911 and I'm extremely happy with it. It has a good trigger right out of the box and has never suffered a stoppage, including with semi-wadcutters. Purists don't like the external extractor on the S&Ws but that does not bother me one bit. Best of all, the gun cost me about $650.00 as I recall.
As I get older, I can no longer benefit from a gun capable of putting rounds in the same hole. But I do like that on a good day when I concentrate, I can shoot ragged hole groups to about 15 yards.
So, lots of really good 1911s to choose from but do your homework. Even the premium companies such as Kimber, will occasionally produce a handgun that must go back to the factory for whatever reason.
Also, do not ever evaluate the reliability or quality of any gun while using hand loads, even if loaded on the alter of the Vatican under the watchful eye of you-know-who.
