Shooting a rare, valuable pistol like that would be taking a very stupid and unnecessary risk. With an unhardened slide and an unknown number of rounds through the pistol already, it would really suck if the OP took it out and shot it, and upon taking it apart to clean it afterwards discovered a fresh crack somewhere. Shoot old guns that have been messed with and aren't worth much. Shooting an extremely hard-to-find example like this that's worth several thousand dollars could turn tragic pretty quick.
Anyway, that's a super-nice pistol and a good example of what were probably the best of the original M1911 pistols in my opinion. The early 1914s had the nice finish, short wide-spur hammer, and flat-topped rear sight. An added bonus is the ball-cut recoil spring housing and no 1913 patent date on the slide. Probably the perfect mix of older and newer M1911 features. Unfortunately as has been said they are very rare and I'll likely never be able to find, let alone afford one.
