I had the sig, ended up selling it due to consistent failure to feed issues with a commonly available brand of ball ammo. I kept shooting in the hope it was just growing pains but >600 rounds and a trip to sig later it still did it. None of my other 1911's choked on said ammo. My advice is to stick to a brand which is known to produce good 1911's and/or go custom and have a real person not just a series of machines fit the gun.
Though i did not know the place, i set out for the land of my dreams.
