You can use whatever qualification course you currently use for everyone else. A few years ago I audited the FBI 1911 transition course. A major component was repeatedly shooting their standard qual course; not a different one for different pistols. Lots of reps to learn use of the safety and basic manipulations.
What you do need to prove is that you are A) safe, and B) proficient.
The safe part comes from following the same 4 universal gun handling rules, but now with the manual safety. The firing hand thumb rides on top and only deactivates it when your sights are on target and you are prepared to fire. It’s right back on as soon as sights come off target. Depending on past experience, this may be a no-brainer or it might take some time to master.
Proficiency is hitting what you are shooting at and not fumbling the other manipulations.
We had a complaint once from an outside agency who was a little freaked when an agent did a search warrant with them and helped clear the house with the 1911 out. Hammer was cocked! And all that. Complete Ignorance. I was asked my thoughts before a full blown internal was spun up. I asked specifically how was he unsafe; I.e. any violations of 4 UGHR? “Well, no.” Was his safety off? “Not that we knew of.” Well, what was the issue then? “He was moving around with a cocked weapon!” Ummm, yeah, and so were you with your 870, AR, or MP5. Did you have your safety on???? RHETORICAL QUESTION
And, there is more preventative maintenance required.
