On the first round and rounds following but not all FTF. Once the failure happens it can pushed in with little force by pushing on the slide.

Ammo used. S&B, Wolf and reloads. All with the same result.
Mags, Willson and Chip mccormic.
the firearm was lubed pretty well.

I don't know what else I can tell you to help me diagnose the problem.. This is my first 1911

I bought it used and the previous owner says this never happened to him.

I would suggest you start troubleshooting by checking your extractor tension - may be too tight. Lots of how to's on tuning the extractor out there that may be helpful.
 
How many rounds between cleanings, 1911's (especially when shot with dirty ammo, or lead bullets) can build up residue in the chamber that will cause this, your STI has a tight chamber (part of why they're so accurate) and can be expected to be sensitive to a dirty chamber.
 
Thanks for the tips. I will try the extractor and maybe get a spring. My buddy shot it and said the spring feels really light compared to his Kimber.

Enefgee. She was fresh and clean. Youre right about the accuracy. Once chambered she is on point.
 
I think that spring tension is unlikely to cause the problem. Putting a stronger spring in it is likely to cure the symptom of a problem without ever addressing the real issue.

I had the same problem with my reloads from putting a little too much crimp on them, which can in turn cause a little bulge further down the case, however you are having the issue with 3 different types of ammo, so unlikely.

I have also had the same problem from using old grease which had become a little sticky. I tried oil and the problem was solved. I would also check the slide and frame for any burrs or roughness. The pistol may also just need to be broken in - if you can tolerate the problem through the first 1000 rounds you may want to consider just running it for now and see how it goes.
 
You can check the extractor for correct tension easily enough. From a handy little book on tuning 1911's that I borrowed it describes removing the slide and then slipping a loaded round up into place and hooked in behind the extractor so it's sitting in the correct position to be chambered. At that point the round should not either fall out or be tightly and firmly held in place. Instead it should be able to hang down just a little from horizontal.

While you've got the top end opened up I'd chamber check the ammo as well. The rounds should easily drop into place and when tipped back fall out cleanly from a clean and dry chamber.

Agreed

Sometimes it doesn't take many rounds before cleaning is needed.
 
Ok. fianly got home.. Took the slide off and put some brass in the extractor and it was tight. real tight. So I adjusted it and will wait to see what range day holds.
 
I have a Sparty in 9mm and the only time I have had FTE I took it home a detail stipped the gun and found the extractor was FULL of gunk. At the time I was brand new to guns and didn't yet know how to take the extractor out to clean it. Been fine ever since:)
And yes the tolerances are tight on this gun and it is dead-nuts accurate. Real joy to shoot.
