1500$ or even a 1000$ to get a reliable 1911 just isn't my experience.
I paid 640 for a NIB stainless Mil-Spec from springfield armory. It ran like a top from day one and has 1000s of rounds through it. The only thing I did until very recently was change the recoil spring every 1500 rounds.
Then I added a new trigger, hammer, sear, etc for no other reason than I wanted to play. The gun ran perfect.
I also just paid 700 for a stainless Colt LW commander, Pre series 80. that gun also runs like a top, but I did have to put 30 bucks into it to get the correct bushing, as the previous owner didn't know the difference between a commander sized bushing and a government sized one . . .
stainless milspecs still go for about 650. expect less for non stainless models. GI models are in the mid 500s. Taurus can be found in the high 500s, though more often they are a low 600 dollar gun- very competitively priced near the mil-spec.
Also Rock Island Armory has a growing following of satisfied owners that spend less or the same as the cost of a new glock and get a reliable 1911 out of the box.
1911s are very easy to clean and maintain. They shoot and point well for many people and have an immense amount of aftermarket support that can let you tune a gun to your hearts content.
They, like all guns, require proper care and lubrication to function properly, and quality mags and ammunition. Quality mags and ammunition does not mean 'ultra expensive' either. Chip McCorm. mags work great in my 1911s, as do surplus GI mags, Springfield factory mags, metalform mags, and others. You don't need wilson 47Ds to get your 1911 to run.
quality ammo doesn't mean high cost either. I run lead through my 1911s for easily 90%+ of their diet.
where people run into issues, in my experience, is not properly lubricating a gun, or running ammunition that just doesn't agree with the gun, or using the cheapest mags available.
Heck I even got some clearance mags from DPMS for less than 5 dollars a pop that run fine in my 2 1911s- They won't feed LSWCs though.
more knowledgeble 1911 shooters and tuners will tell you better than I can that 1911s, because of their popularity, have been pressed into service in a variety of ways outside the original scope of their design. They have performed admirably in these roles- however, along the way some hiccups have come up. Predominately associated with poor magazine design or poor gunsmithing fixes because the proper function of the 1911 was not understood by the user.
I'm not calling out the other posters who have not had good luck with 'budget' 1911s (600 dollars isn't budget in my book! my 1911s are the most expensive guns I own!) but considering the cost of many semi-auto, quality handguns these days, 1911s are very competitively priced, reliable guns for many users. I urge you not to write them off as a viable option for a quality handgun.
