Just a thought. It may be the wrong handgun for her. My wife had the same issue. Her hands had trouble clearing the safty and racking slide. Our cure was a S&W 438, change the springs and a little massage of proper internals, pull is down from the 10 lbs. to 6.5 lbs. Much better trigger pull and smoother action all around. Plus less chance of misfire than a semi auto when it counts. It really depends on your mindset of why you carry. We carry for protection and do not need people knowing or care about the cool gun factor. Its about reliability and ability to reliable action the wapon efficently when needed.

some of the typical misconceptions that are the reasons why men chose revolvers for their women. Not that the women get any choice or any proper training.
Are there people that have problems with racking the slide of a semi-auto handgun? Sure. However, any healthy person should be able to rack the slide using the proper technique. Since most men have zero formal training when they get their women handguns, they teach them the wrong skills, including how (not) to rack the slide.
Now, lets assume for a moment that a person can not rack the slide. What's the difference between a loaded 6-shot snub-nose revolver and a loaded 13-round subcompact semi-auto handgun? It takes one reload for the revolver to get close in capacity. How about a 16-round compact semi-auto handgun? That's close to two revolver reloads.
Semi-auto handgun malfunctions are typically related to magazines (mostly wear-out or dirt) and user error (mostly limp wristing). Clearing those malfunctions requires to rack the slide. However, revolvers are not necessarily as reliable as one thinks (see video below). A
misfire is something completely different. It typically relates to ammo and sometimes light primer strikes (i.e. the gun). It can happen with both, revolvers and semi-auto handguns.
In summary, get your women some training. There are lots of firearm training schools out there that have classes specifically for women. After such training, let them decide what they want. Lay off the nonsensical gun talk ("cool gun factor" ?).
