I wouldn't pay $1400 for it . . .
For about $1400, you can buy a mid-to-low end Wilson or Baer or a top-end Kimber or Springfield -- with several hundred bucks let for holsters, ammunition, and so forth. On a strict monetary basis, there is no way (IMHO) this Colt can compare with other 1911A1 options. Further, the ivory grip may be cosmetically nice, but how effective would they been with mud, sweat, blood, etc. on them?
