i don't really know much about building a 1911 but if your looking for a quality lower end 1911 platform rock island armory makes a nice firearm that lots of people say compares to the lower end kimbers in quality. so you might try taking a look at that
I'll second Axxe on that - you would be better off buying a used 1911 and then try to upgrade when the wallet allows.
Like anything, there is a learning curve. Watch Nutnfancys on YouTube - he has a pro work on his 1911 for accuracy upgrade. Little tricks to fitting parts etc that are difficult to learn from books etc. N if you screw it up, then you have to factor in gunsmith fees and the price of the whole project goes up. Worse yet, you could end up w expensive project that doesn't shoot well. .
Go to your gun club often & local ranges. Bulletin boards have ads. Some poor SOB will be either be getting married or divorced & both are often the cause for liquidation @ fire sale prices. Hell, one soon to be X-wife got so mad she sold her hubby's Colts & Kimbers for $1 dollar a piece.
Yeah, Life ain't fair but I suppose you already know that...
I have a RIA 1911 CS that I bought used with plans of use as a carry piece. However I quickly found a quirk with it. At the range after about 50 rounds, it begins to fail to close the chamber all the way every third round or so. So far I've found no one who knows why this is happening, but I think it might be why it was for sale in the first place. An acquaintance of mine is likely going to buy it from me in the next month or so, for some reason he is not as concerned with this as I am. It's probably just a fluke, but it makes me not want another RIA. Sad, because it's a pretty nice shooter when it actually works. At $350 used, it's definitely cheap but it also malfunctions.
First, try using ARMSCOR 45ACP ammo, I buy mine from ammotogo. also make sure you are using an org RI mag. Look inside the chamber (left side looking down into the chamber, see if there are any brass rubs on the slide lock near the mag. if so you can file it down slightly.

I bought a Para G.I. Expert this past fall and its a very good 1911. Its more accurate than my brothers Ruger. Its also American made which is another plus.
I have a Taurus PT-145 thats been my daily carry gun going on 5yrs. Its a darned good carry gun. It has never malfunctioned, its accurate for a short barreled semi, and it holds 10rds. I like this Taurus alot. Ive heard all the crap online about them and most of it is BS. Im not saying they dont have issues but who doesnt. Taurus is a good reliable gun. If you like it buy it.
