Your gun,do what makes you happy.
If ;twas me,I'd recognize the Delta Elites are few and have value as originals.Folks would stand in line for a chance to buy yours...unaltered.
Generally,I have no qualms about altering a firearm to whatever I want,unless its uncommon or unique.There are a LOT of other 1911 s to work with,including the Philippine ones.I actually prefer them to Croatian Springfields.
I'd think about how really good 1911 craftsman are not easy to find,but hacks are.
Having custom work done is not cheap.
If I had one and did not want to shoot full power 10 mm loads,I could buy a BUNCH of Starline 10mm brass and Montana Gold bullets for the price of a conversion...and load it to a level I enjoy.
I believe there is an LEO level mild 10 mm factory load.
I have an original Colt 38 Super slide (No,I don't want to sell it) in very nice shape. I considered using it for a 10mm build. What stopped that idea is the Colt written "38 Super" stamped on the slide. I did not want a mismarked cartridge designation and I did not want to mill it off.
As has been noted,simply swapping a top end as a back and forth conversion is not real practical because it requires an ejector change.You could do that...but,why?
I'd leave it a Delta Elite and load it to suit me or trade it off.If I wanted a custom project,I'd go Caspian,STI,etc
But,thats me.Its your gun
