Hi guys, I have a Springfield "GI .45" Mil-Spec 1911. The gun has worked nearly flawlessly for over 8 years now. One minor problem rears its ugly read from time to time, though: if I use the slide release (or slide stop, if you prefer) to reload a fresh mag, it has a failure to feed the first round, getting stuck about halfway. Is this indicative of a particular problem with the gun: recoil spring, slide stop, mag, ammo, etc.? Or should I just use the tried-and-true "sling shot method" exclusively when reloading? Gun: SA 1911 Mil-Spec Mags: Metalform 7-round
Ammo: factory ball ammo (American Eagle, Blazer Brass, WWB, etc.) Thanks. |

Quoted: How many rounds do you have through it? The reason I'm asking is that sometimes recoil springs wear out. Maybe it's time for a new one? It's not like they're expensive or anything..... True, although the spring is nearly a decade old, I really don't have an Arfcom-level number of rounds through it...I probably average about 100-200 rounds per year since 2004. (Shooting .45 is expensive, especially these days!) |

Quoted: I'd try recoil spring, and then check out the Extractor. That tends to be majority of the failure to feed issues, short of magazines. Will do. Just out of curiosity, how does the extractor affect feeding, as opposed to extracting? Not doubting you; I've read this elsewhere too. Just curious. |
The slide is pushing the round out of the magazine - the case head starts to ride up the breech face but the bullet has contacted the feed ramp so the case head and rim are at an angle to the breech face. The extractor must have sufficient clearance to accommodate the rim at these angles. If it doesn't, the case starts to jam in the extractor which can stop the slide. Take the slide off and remove the barrel. Take a round of the ammo you shoot and stick it under the extractor - observe the round hanging there on the extractor with the nose down. If it's tight and the round doesn't have much of an angle, the extractor needs tuning.

If the extractor tension is within spec, you're probably looking at weakened springs. A Wolff spring tune up kit is cheap maintenance. I do prefer it, but the "official" name of the part is actually listed as a SLIDE STOP... and I use it as such. The extra 1/4" of pressure you exert on the recoil spring when you properly slingshot your slide to load a fresh magazine would probably alleviate your FTF condition. Just sayin |

replace the recoil spring with a new 16lb or 18.5lb.
If the slide stop release or release should drop the slide and load a round with no problems. If it does not, I would fix the issue. ie extractor tension and a newrecoil spring. "open position and serving as indicator to show that the empty must be replaced by a charged one before firing can be continued After placing magazine in the grip the breech slide is released by depressing the handle j A slide stop act aated by the magazine follower to arrest the breech slide in the position when the magazine is empty been heretofore described and shown in United States Patent No 708794 granted me September 9 1902 but the of the slide stop as an integral part of handle of the pivot pin securing the and the breech slide upon the frame herein shown and described is a novel improvement which reduces the number parts and simplifies the dismounting and of the arm " |

Does this gun have the ILS safety system?
If so, the recoil spring is likely underweight to compensate for the heavier mainspring. It wouldn't be a bad idea to buy a new mainspring cap and a 19# mainspring, and then go with either a 16# or 18# Wolff recoil spring. |

If I read correctly, the problem only occurs with a full mag, with the mag spring at maximum tension. The rest of the mag has no problem feeding, correct?
The round chambers by slingshotting. It sounds like the spring just doesn't have enough force to do the job with the way the gun is currently set up. It's also likely that the extractor is adjusted to provide excess tension, and the recoil spring runs out of juice getting the round underneath the hook. Could be the extractor hook needs a sharp edge taken off of the hook as well. Check and adjust extractor tension and dimensions |
