One of my students today was using a Kimber Micro 9 CDP.
I’m not overly familiar with this specific firearm and need some input here from others who may have one.
After firing, the hammer stays cocked, which is typical for pistols but, here’s the but, the safety will not engage unless you really force it with both thumbs of hard pressure!
If the hammer is unclocked the safety will engage with ease. I’ve looked at a few youtube’s and it does appear that the safety should engage easily under all conditions.
