My Springer GI had a problem with not going into battery, right out of the box. Tried a stronger recoil spring, tried a shock buffer - nada. Put about 600 rounds through it - with careful cleaning every 100 rounds. Nada. Had a gunsmith tune the extractor. Nada. We're talking WWB ball ammo here.
After doing some reading, I tuned the extractor myself by pulled it out, sticking it in the hole half way, and bending it. After some trial and error, it seems to function just fine now. If it'll go 500+ rounds without a hicccup, I'll consider it good. I had Novaks installed recently, and I can finally hit what I'm aiming at.
Considering that the extractor is "tuned" by bending the damn thing, I'm honestly suprised that any mass produced 1911 works 100% at all out of the box. Seems to me like dicking with them is kind of a given. Oh well, I still love it - "idiot" scratches and all.
