spend it on something else, i have a nighthawk custom GRP recon hence the screen name. its a absolutely wonderful gun! it was and still is sometimes my carry gun, but for the actual resale cost your paying 500 more than the gun is actually worth imo. for the money your willing to pay you could go and get yourself 2 new guns or 1 gun all the neat little toys and have money left over.
i am a huge 1911 fan and have many of them all sizes and shapes. but the T3 if its even lightly used is still to high a price. have the dealer knock off 3-500 off then maybe.
