Wilson Combat makes a number of their 1911's - in 9mm - with 1" guarantees at 25 yds.
Same for Les Baer and STI.
I though Les Baer was 1" at 50 yards? Hand fitted to the nines. I would say a step above wilson or sti. That is reputation, I dont have one. If the OP has good taste and budget for a Smith 41 -- Baer is probably the way to go (I am also assuming they offer a 9mm based on prior posting)
I have an STI Target Master, 6" barrel. Now discontinued. That was offered as a 9 or 45. Those were $1500 or little less dependent on the dealer. Mine will hold 2" at 25 yards, factory 185 loads in 45acp. I was not aware of any STI guarantee. I dont have a machine rest, but I can hold (and see) an inch with a good bench rest - so I am pretty confident. Probably subtract 1/2 inch for a machine rest test. Its a great gun and worlds better than my colt gold cup. After the STI experience, I plan to have my gold cup re-barreled. The 9mm should be at least as good given the heavier barrels. Target Master is (was) kind of an entry point for STI, you can pay double for, I assume, more performance. But, I just dont recall seeing any guarantee. They also have models that accept optics and remind me of a 1970's pimp mobile. I dont care for the solid guide rod takedown. You get used to it. It is a tight gun, yet very smooth. They recommend Lucas oil and clean after every shooting. The trigger started out 3 1/4 pounds and now running close to 2 1/2. It adjusts for over travel and breaks clean. Good value, IMHO. This model has a very fancy rear sight. I dont know if they offer that any more. Its has three independent settings.
