Some might say, it is a shooter grade pistol. I do not shoot mine, and I would not use the one posted as a shooter. They just did not heat treat these old pistols they way they do newer handguns.
Yes there are properly heat treated slides, and they are pricey and will have to be fitted to the frame. Shoot what you have and just limit your range time with the gun.
I asked our tool maker at work about heat treating. During production at war time they used torches to spot heat treat and a quick quenching most probably in oil. If you knew the type of steel used to make the slide/frame then you could have your gun heat treated, but finding that info and being able to verify that its correct would be finding the needle in the hay stack look like a simple chore.
