STI Eagle .45 Jam

[mont1120]

Well I am truly baffled now. Last Sunday my Eagle .45 started stovepiping the first round of the mag jamming it nose up between the barrel hood and the mag. I figured it was a dirty mag and no big deal. Cleaned the mags, went to the range today, and no matter what mag, MBX, STI, 10 or 15 rounder, the first round got jammed.

This happened with MG RN, Blue Bullets 230 gr, and Xtreme RN, with varying lenghts, nothing mattered. 1.24, 1.22, and 1.2.

Got home, checked my measurements, and for the life of me nothing jams now. What on this earth can cause this condition.

Extractor tention

Brownells has a good article on adjusting the extractor in a 1911, also the tools needed. I used an empty shell case, drilled a hole thru the rim, used a paper clip to make a hook and my trigger pull gauge to check the tension. Not sure if the 45 uses the same tension, but the 40 is 24 to 28 oz lb. You may want to also invest in backup extractor. Good luck

Just to be clear, this stovepipe happens when the loaded round is going into battery, does the extractor still cause this type of problem?

The jam occurs when the rim of the case is sliding under the ejector. Too much tension and the case cannot move into place. Also check for a burr on the breechface. I had an edge that would not feed and it was because of a burr on the firing pin hole.

To check extractor tension, remove the slide from the frame and take the barrel out of the slide. Then slip a round up the breech face under the extractor hook. There should be light resistance as you do this, not a lot. Then put the round under the extractor hook and square against the breach face. When you hold the slide horizontal, the round should stay in place. Adjust according to results. It's not rock science and no special tools or spring loaded gages are required.
