This is my first time posting on this forum, so any help will be greatly appriciated. I have a friend with a 1911 Colt, marked model 1911, Colt logo on left side, serial #782XX, on the right marked "Colt's MFG. Co, Hartford CT USA". It appears to be a .45 but it is .38 Super, however there are no markings indicating the caliber anywhere. Please help me to identify this.
