If you are talking vintage 75B, they havent changed hardly anything since the gun started production in 1991-92. If by vintage you mean a 75 Pre-B then they are significantly different. The sights, slide stop, mags exc are all vastly different. The pre-B can be modified to take B magazines, but as for the other parts you may be SOL. They are all absolutely great guns though. They are more accurate out of the box than many custom built guns, as well as being dead nuts reliable and built like a tank. Cant really go wrong if you find on at a good price, problem is the price keeps going up almost monthly.
