Don't know whole lot about 1911 ... Budget would be about 850 max
Reliability is important to me, more so than an amazing trigger or being a tack driver.
If you want reliability under $850, go with 5" Government size RIA Tactical.
Why?
RIA Tactical (made by Armscor) is the "Glock" of 1911s due to generous chamber mouth that will reliably feed even sloppy 200 gr lead SWC reloads. After firing several hundred rounds of dirty reloads, looser tolerance RIA Tactical will keep feeding and chambering rounds while my tighter chamber Sig 1911 will slow down and require help putting it into full battery due to tighter tolerances.
As to accuracy, around 1" groups at 15 yards on par with my Sig and slightly larger than 2.5"-3" at 25 yards when my Sig will produce around 2" groups. A friend bought a RIA Tactical about the same time as I bought my Sig and after 7000+ rounds, no parts breakage other than recoil spring replacement for both pistols cleaned only with Hoppes #9 and lubed with BreakFree CLP/motor oil.
Of course, since your budget is $850, I would suggest a 5" Sig 1911 which are all made on stainless steel frame/slide regardless of finish with match grade barrel and trigger. Like S&W 1911s, Sig 1911s have external extractor which is way more reliable and frame-to-slide fit is soooooo silky smooth, even on the base XO model. The black "Nitron" finish over stainless steel is very durable and my Sig doesn't even show hardly any wear while my friend's RIA is showing "character".
How about Sig 1911 Texas Star model for $679? -

(Don't worry about the barrel sticking out, the slide is pulled back on the picture)
And here's my railed Sig 1911 XO. Notice the "thicker" muzzle of match grade barrel that fits tight with the bushing (RIA and even most domestic brand 1911s will not have internal fit/finish as nice as Sig 1911 and most do not use match grade barrel/trigger). None are made from stainless steel unless they are specified. Some won't feed SWC reloads reliably and shorter commander size models will have more reliable feeding issues.
Match grade barrel with no leade to reduce gas leakage
Clean finished internals with smooth transition from ramp to barrel to reliably feed even SWC bullets
Checkered frontstrap and beveled slide that many other 1911s lack. With aggressive factory "sand paper" grips and checkered frontstrap, you get a firm grip even with sweaty hands. For RIA and other 1911s without checkered frontstrap, you can add Wilson Combat checkered frontstrap for $10 -

Slide-to-frame fit is tight yet slide racks with buttery smoothness.
