First off, the 1911 mindshare is found mostly at

But you got a double-stack .45 Frankengun that is not strictly a 1911, and looks like it may have had a questionalble past. The list of things that could be off is very long.
If you knew the gun and mags hadn't been Buba'd, and the slide, barrel, and frame were actually fit by a competent gunsmith, the next up, and without being able to handle the gun, would be extractor tension.
Take the slide off, remove the barrel, firing pin stop, firing pin, and extractor. Clean up the extractor and take a Q-Tip and cleaner to the extractor channel in the slide. Put the extractor and FP stop back in to hold the extractor in place (you might have to hold the FP stop from falling out). Leave the firing pin out. Now, with the slide right side up, slide a round up under the extractor, not quite up to where you see the circular wear mark on the breachface.
The extractor should hold the round pressed against the opposite side enough that you can jiggle the slide a bit without the round falling, but a little pressure (guestimate 3 lbs to be in the ballpark) with your index finger should release the round.
If you need to reduce the extractor tension, be mindful that they aren't that cheap and can snap if not done carefully. You are essentially bending the thing along the gentlest curve possible. There's a way that involves a vise with the plastic/padded handles of a pair of pliers pushing one way (each end), and a single padded plier handle pushing the other way (the middle). Think about it. Most vises come with a warning not to do this sort of thing.
Sweeney, who's a gun rag writer but figures he can write gunsmithing books, suggests putting the extractor ass backwards part way back into the slide, and bending the extractor tip end against some surface. Gunner at Armco (see sponsors above) will sell you a replacement extractor should you break yours.
Messing with the either the ramp on the frame or the barrel ramp will earn you the Bubba award. If they haven't already been messed with, they are not the problem. If they have been messed with, and they are the problem, then the gun won't be worth fixing.
That's a start anyway.
Ok I thought I fixed these FTF problems, last time I used winchest JHP's there was zero FTF. I went to the range with some CCI 230gr FMJs and every bullet just nose dived into the top of the chamber and did a FTF and most of the time set the bullet back into the case.
