Last Thursday I took my NIB Springfield GI out for our first date to the range. I had broken it down and cleaned it a couple weeks ago (and did so without an idiot mark) and at the range I put a couple drips of RemOil into the slide rails, the base of the hammer, and a drop on the feedramp. I also loaded my mag (7 rounds) and put three drops of oil on the top bullet - one at the front of the cartridge and one each on the side, letting it drip down into the insides of the mag.

My first mag went well (3 yards...the 10 yard PVC holders had disappeared, and no way was I going to shoot at 25 first-time-out) with my first 3 rounds cutting out the center of the bull. Then the FTFs would start. The gun would fire and eject the empty, but then as the slide went forward, the round would not strip cleanly out of the mag. It would hang up - sometimes just barely touching the feed ramp or sometimes beginning up the feed ramp. Trying to retract the slide by hand to clear the jam was difficult (once I thought the gun was locked up) and I could not drop the mag while it was jammed. Several sharp pulls would finally free the slide and the round would fall freely in the chamber (or fall out of the gun completely if I had jerked the gun).

It got to the point where every round was doing this. A couple old Army vets were there shooting. They came over and offered their advice. One guy claimed to be an armorer, and his diagnosis (through the open action; i.e., he didn't field strip it) was a rough feed ramp. He recommended a buff job w/ a Dremel on the ramp. So, I gave up and packed up the 1911 for the day.

Got home that afternoon to break it down and see what I could see. I read the warnings here & on the m1911 forums about using Dremel tools. Wary of screwing up my new gun, I figured I would see what I could see. A wipe-down with Hoppe's showed the feed ramp to be pretty smooth - not mirror quality for sure, but it sure wasn't as rough as he made it sound. As I was reassembling the gun, I noticed my slide release. The inside of the slide release (where the empty mag follower would bump it to lock the slide back) has the glimmer of brass on it - as though rounds are striking it while passing by.

Knowing anything is possible, what is the probability that this little tab of metal may be impacting the live rounds, thus preventing their upward and onward journey into the chamber?

By the way, the gun is 100% original; ammo was 230 FMJ WWB and Blazer Brass. I read some of the other threads @ springs, new mags, new mag springs, etc. I'll do that if I have to, but hope I don't need to go that far.

If the gun jammed with the round not feeding out of the mag or just barely getting to the feed ramp it is not a ramp problem. DON'T USE A DREMEL.
This sounds more like a bad mag problem or as you suggested the bullet is hitting the slide stop.

Try hand cycling a round or two in the basement pointing to a foundation wall to see if you can duplicate the jam in slow motion. I would use the WWB not the Blazer. If the slide stop is being hit by the bullet you should be able to see that and touch it with a file to get clearance.
 
Yes, it could be bullets hitting the slide stop. Polish it where the brass tracks are located, as well as the feed ramp.

Light polishing with a bullet-shape felt wheel & buffing compound will not remove metal and change its shape..

Do Not put oil on the ammo, or in the magazine.

It is not only not necessary, but unwise for several reasons.

I would wash them out with solvent, and if you just have to lube them, use Remington Dri-Slide spray lube lightly.

In addition to what 10x and rcmodel suggest:
Do you have another magazine to try?
You might also want to check the extractor tension:

Those two are easy to check, but it's still a shame that you have to check them on a new pistol. If it's anything else, I'd contact Springfield and have them make it right. It should feed ball reliably out of the box.

That's what I woulda thought...

The dudes at the range started running down Springfield and the GI model in particular. While I certainly am not happy about the situation, I'm not about to throw in the towel yet.

I'll try a couple of these ideas and see what happens.

Help me out here.

Does the WWB .45 ammo use a truncated cone or flat point bullet like some of the other WWB calibers?

If so, that right there might be your problem.

Nope. This is round nose 230 grain FMJ - standard .45ACP ball ammo. And these were the first rounds down the pipe. I didn't even get 20 rounds downrange (in fact, I'm not even sure if I got 14!) before I gave up.

You know...GaryK...I just might give Springfield a call this afternoon. While I'm not crazy about having to be w/out my 1911 for a couple weeks, I'm even less crazy about screwing something up. BTW - where about in Houston are you? I'm Lake Houston area.

Two things .....

1. Bullets should not be hitting the Slide Stop on their way to the feed ramps. Use a file to remove what is necessary to prevent this interference. Be EXTREMELY careful not to remove any metal from the bottom edge of the Slide Stop ...........it is this area that contacts the magazine follower to lock back the pistol on the last round. GO slow .....................

2. Springfield Armory has a bad habit of setting their Extractor Tension too HIGH ............ and this can cause FTF's . I have seen this on many S.A. 1911 pistols. I guess they feel the gun will break-in and the extractor will loosen up with use. Problem is ..........this can take hundreds of rounds of ammo -wasted. So CHECK the extractor tension ........something you should learn to do if you are going to keep the 1911. It is a WEAR item and will need adjustment and / or replacement in the future.

To follow up on the extractor tension issue, remove the extractor (and firing pin for safety reasons). Then try feeding rounds. If the rounds feed well that way, look to the extractor for problems. You still may need to clearance the slide stop to clear the nose of the rounds.
 
Follow-up...

Went out to the garage this afternoon and manually cycled rounds through the gun...40, 50 times. Did it slow, did it faster. I could not duplicate the problem I was having at the range last week.

However, I did pull the slide stop tab out of the gun. And, again, the tab that rides up on the empty mag shows that brass has been rubbing against it. I'll have to do a little file work to smooth that out. It's not much - but it's rubbing.

I'll do this first and see how things go.

I'll check the extractor, too, just in case.

Thanks for the help, guys.
