Brand new Springfield G.I. purchased February 2nd.
Today at the range: 150 rounds fired. (WWB and Blazer Brass 230 grain ball) Fed it using factory 7 rd mag (5 full mags) and had two FTB's. Both on last round, first and third fully loaded mags. Remainder fired using two different Wilson 47D's. No issues whatsoever. Oh yeah, took two spent ones to the upper forehead. Thought only my Kimber did that. Ha! (Actually not sure if they bounced off lane cover) Anyway, I'm happy. My second Springer G.I. and just like the other one...hits right where I point it. Planning on shooting the crap out of this gun and looking forward to breaking in further.

Congratulations on the new pistol!
Only 2 spent casings to the forehead? Lucky. Mine did the same but more frequently. I'd get hit in the head, glasses, nose etc. 
I adjusted the extractor and installed an EGW flat bottom firing pin stop (with a very small radius on the bottom) and that cured that issue.  It is a real easy gun to shoot. I really like the old-school look the G.I. .45 has.
The FTB may be due to the newness of the pistol. I would give the mags another chance. I have used the factory ones and have not had any problems with them. |
| What is a FTB??? My GI came with a piss weak recoil spring (think 12-14lbs) and would occasionally fail to push the rounds up the ramp and out of the mag. Switched to an 18, problem went away. Put over a thousand through it since, no issues. Was catching brass in the forehead occasionally with mine too, the stock extractor wasn't tuned right. |

Round is chambered, but slide has not quite fully returned to "battery". In my experience with 1911's this usually means only about 1/4" short of slide being fully forward and ready to fire. What you described is FTF, or "Failure to Feed" Both you and Walther22lr mention adjustments to the extractor. I would be interested to understand more about that. I have no experience in "smithing" so any education would be appreciated. |

Always called that a failure to feed, I know what you are talking about now. I just bought a Ed Brown Hardcore extractor and tensioned it until it felt right.. Problem went away. I'd try a 18lb recoil spring and new extractor, or look at these to see if it is done correctly

Quoted: My Les Baer hit me in the face on the last round of the mag for the first 400 rounds or so. A few times it hit me with the case mouth and left a half circle shaped cut in my forehead. It has calmed down now and doesn't do it anymore. So ............ you're saying your Les Baer used to bitch slap you but knows who's boss now eh? |
| I finally got to shoot my GI today for the first time. Only had time to run 50rds through it. It ran pretty good, but I experienced the same problem with the slide failing to go fully into battery. I'm going to try a 17lb spring and see what happens. IIRC, the factory spring is 16lbs? Or maybe I should just go straight to an 18-18.5lb spring. |

Give it another 200 rds or so to smooth up the slide / frame fit. |

Give it another 200 rds or so to smooth up the slide / frame fit. I tend to agree. I believe 250+ rounds through ANY new 1911 is required before coming to any conclusions. And, from what I can gather...mags are a critical component relating to the FTF and FTRB issues. Some 1911's seem to like one brand of mag over another. As I've already stated, I don't claim expert status, but experience with a few of them and testimonials lead me to this belief. |

That's some good stuff. Appreciate it. |
I have a simular thing with a Champion LW GI, if I tr to do a "brass check" it WILL NOT GO BACK INTO BATTERY without fully cycling it. When I'm shooting it I've never had it happen, but if I'm just messing with it and ride the slide home, it will not go that last 1/4" 
Locking lugs must be tight? |
