I will respectfully disagree with you. What happens when the job goes wrong? Who is responsible for replacement of the damaged slide?
Are you 110% certain that there are no design changes to the slide over the years?
All valid questions. Do you want to be the paying guinea pig for this experiment???
If you can buy a second, sacrificial slide to experiment on that would be helpful. That way, the slide serialized to your frame and barrel can all stay together as a complete gun.
