before my boat sunk and house burned down, causing me to loose all my guns, i had 4 1911's. The sig xo has ran like money, never failed. I now use it as my nra instructor gun. My SFA ran like a typewriter, and now another member on the forum has it. My dad really loved our 2 colts, but now they are boat anchors. They also ran like typewriters...If I had to pick one to put my life behind, it'd be the sig. Great lock up and never had a problem...
SFA milspec SS
1991 series 80 colts x 2
Sig X0
Only money i put into the guns were new sights, bigger beavers and smaller grips.
