The only time I ever shot steel cased ammo in a pistol, it was Winchester USA Forged 9MM 115 gr. It was on sale, cheap and I bought 500 rounds. I managed to shoot maybe 20. It choked every gun I tried it in. My 1911, my 365 and even my G17 refused to work. FTE's with one round that I had to use a tent stake to punch it out of the chamber. All 3 guns are flawless with brass cased ammo of many different varieties, but none of them would run this stuff. I ended up using it in a trade to sweeten a deal. He said he had a 9MM Blackhawk and they worked in it.
