I have over 30K rounds of Wolf/Tulanmo ammo thru my West German made(carbon steel slide) Sig Sauer P226. Not 1!!! Ever a problem with that ammo as far as reliability. Dirty? Yes! Stinky? Kinda. I am a member of the Elks, and we do a charity shoot every year for The Disabled American Veterans. I supply a lot of the weapons. Fundraiser $$$ buys ammo. Back when the Obama ammo scare happened a fellow Elk bought 5K rounds of Wolf. Ol' Siggy burnt thru most of it in a week. Dirty as a MF, but worked without a hiccup. Spray in some WD-40, rack the slide a few times and good-to-go.I was more worried about my mags holding up. They did, and still do. Gun needs a new finish as the old one is worn off. The older internal extractors are great. Don't know about the newer Stainless Steel slide with external extractors. My pistol loves all/any,absolutely any 9mm. From Glazer to +P+ full sub machine gun ammo.
