Re: Your new .45 and handloads
some of this has been recently discussed here:

The only problems I have had with hand loads in my customs were due to me belling the ammo too much.
That said, a brand new, out of the box 1911 should run hardball no problems but might need a good fluff and buff of the chamber, hood and ramp to run flat nosed or hollow point ammo without getting into a 3-point bind. Takes 5 minutes with a dremel and feeds like crazy.
That said, I do not now, nor have I ever owned any of the pistols you mention, but I have worked on, shot and talked to people who do.
That said, the Sig and the SA should run fine with any type of handloads. (might still need a bit of polishing)
The Glock has hex rifling that causes extreme stripping of lead bullets quickly fouling the bore and your pistol will quit working or explode before you have too many rounds through it. Read the Glock manual, it tells you not to use cast bullets!
Kimber will both be at the upper limit if not over your price range and may or may not run. I know there are a lot of people who love their Kimbers, but there are also a lot of brand new Kimbers that just plain do not run correctly if they will even feed in the first place.
In short, hardball, including well made <span style="text-decoration: underline">should</span> run fine in any 1911, most could use minimum polishing in order to run anything (again made to spec) Sigs will cost on the high end, but are well made. Kimber is a gamble, and again on the expensive side. Glock and cast bullets = big no no.
A basic SA, Taurus or Para will get you in for around $500.00 the fancier models may have options you do not like or need.
I would rather start with a basic model and change out the grip and thumb safeties to suit myself than spend the extra money for the Loaded version. Even if I had to take a frame to a gunsmith to put my preferred high rise grip safety on, it would still be cheaper than getting a "loaded" version and I could pay for any modifications over a period of time instead of up front.
