I don't presume to know your budget, but I'm a fan of the 1911 platform. if you are looking for a government sized (full sized) 1911, and want to spend under 800, I think the Springfield armory Range Officer rules the day. Great gun for the money. For slightly less money, say 600-700 their are the STI Spartan, Para Ord GI, Springfield Armory mil-spec, and Remington R1. PERSONALLY, I've inspected 3 R1s and all have had some issue with meeting specifications by a wide margin. I hear they can be good, but definitely look it over closely prior to taking possession.
For a true budget purchase, in the 450-550ish range, are the Citadel, RIA, and American Classic. I own at least one of all of these and frankly they all run like a top. If you like ambi controls and FLGR, and dont mind a gun that is park'd, go with the RIA offerings (they also produce citadel, which is imported by legacy arms). If you like extended controls, bluing, and 3 dot sights, go with the American Classic II. It is, and has been for me, and exceptional 1911 right out of the box.
Currently, I'm down to 4 1911s and the ones that stuck around are: a lightly modified SA Mil-Spec 45acp in stainless, an RIA Tac in 9mm, a Citadel CS in 45acp, and an American Classic II in 45acp. I sold off an original colt LW commander (pre series 80) because it did nothing these other, cheaper guns couldn't do.
The big thing about 1911s is proper lubrication. A lot of new 1911 owners lube them like they would a glock, and this can sometimes lead to issues. I grease the rails, bushing, top and bottom lugs, and oil the disconnector and hammer (lightly). do that, and run spec ammo and even cheap mags will generally feed all but the most persnickety JHPs. If you are a reloader and you are running 200gr H&G 68 LSWC clones, keep them under 1.250 OAL and match the shoulder of the nose with the Ogive on a ball round for length and they will feed EVERY time. if you are running a non-true H&G 68 clone, (like the mold from lee precision) all bets are off and you might actually have to go with a slightly longer OAL, which might bind in some mags.
