I'm not a 1911 guy myself but will ask the same question I would ask if someone stated they had their mind dead set on a particular modification, etc.
Other than having a replica gun for use on the range, etc, do you have a specific purpose you want the gun to serve? If the purpose is just that, a replica gun, that is not a bad purpose, just checking to see if you have intention to shoot competitions, carry it, nightstand gun, etc. The purpose may help the folks here tell you which of those modifications may be more desired, less desired, more or less functional, which should be prioritized, etc.
