I bought a NM serial SS milspec Springfield 1911 in 2011. I have put only about 500 rounds down the tube, however, I have never had an issue with FMJs. When i first got it I had some problems feeding gold dots, however after the first box of 100 FMJ it was fine and all hollow points I have tried not work fine; however, I stick to Winchester Rangers. In extreme conditions (lots of dust and bellow freezing and about 200 rounds later in pawnee grasslands) the slide would get visibly slow, however, it still functioned. I trust it with my life, but it is too heavy for CCW and it lacks a light rail so it is not good for home defense, so, It is just a range gun for now.
