I just got my 1911 back yesterday.
When I first went to the range a month ago. The last two rounds would only feed halfway into the chamber. I sent it to a gunsmith to get the tension on my extractor adjusted. I received it yesterday. The smith tuned the extractor, and polished the chamber. He told me that he fired two clips with 2 different types of ammo, and had no problems. He also told me that the spring is abit heavy, and that the factory mag did not pop out after the he fired the full clips. The smith told me I would just have to pull the mag out of the well after shooting the factory mag. He didn't have any 7 or 8 round Wilson, or Chip McCormic mags in stock yet.
Today I went to the range with 150rds of ammo, and spent them all. Just about every time I fired a mag. The last round would only feed half way into the chamber. I could pop out the mag normally, and the slide stop engaged, when the half way cartridge was extracted. I then reinserted the last cartridge into the empty mag to fire it. After the final round was fired, the mag would not come out of the well unless I locked the slide stop into place, and pushed the mag out through the chamber while holding the mag release button.
The 10rd still only feeds halfway into the chamber, just like it did last month. I now consider that mag a lost cause.
What do you think the problem is? Is the extractor tension still to tight(or loose)? The spring to heavy? Or that I need to try a new mag? Because I sure don't know...
