Tuning for Reliability

[Sergio Natali]

Out of my range experience (mainly with 1911 GLOCKs and CZ) I had stovepipes when my loads were too light fo the recoil spring or the recoil spring too heavy, or problems with the extractor (worn extractor hook, tension too high); I had failure to feed generally when I had faulty magazines, but could be caused also by too much extractor tension, or worse still a barrel somehow throated imroperly.

I understand the theory, but in practice my pistol short-strokes on 115 and 124 gr Winchester White Box ammo with a 16 lbs recoil spring, as if it's asking for NATO loads that I'm reluctant to use.

It should work fine with WWBox 115 grs, at least with the original recoil spring. I'm suspecting the extractor might be the culprit.

Let's make a simple test. Load one round and shoot it. does it lock open?

Can you see any possible flaws to the extractor claws(tips), or the breachface? Does the extractor move freely, and to it's full extent in the extractor channel?
