I sort of cringe when I see people suggest women should get a very small gun as they are often hard to shoot and have excessive recoil (not all of them). I generally suggest people go rent a few guns and/or let me go with them and bring a few examples to try.
I think new shooters would often handle full size 9mm pistols better than the very small guns. Many people are intimidated by big guns even if they are easier to shoot. A lot of large 9mm pistol slides are easier to rack with more surface area to grip.
In my post (not that you were referring to it), I was not suggesting a revolver, but rather, if she went revolver, one with a trigger similar to the LCR trigger.
While there are various reasons for weak hand strength, and different kinds of weaknesses, a long, hard (that's what she said!) DA trigger pull, IMO, is much harder to accomplish for a weak hand than racking a slide. I notice this even with my own hands. When I practice weak hand drills, I "feel" like I need to exert more force to work a DA trigger than to rack any slide. Doing weak hand DA trigger practice is much harder for me than other weak hand firearm manipulation.
Other than the S&W EZs, and similar I would agree that a larger pistol is often easier for a weak handed person to manipulate than one with less surface area. From my own use, I find my CZ Omega harder to rack than my FNX-9 because of the skinny slide design on the Omega. The FNX, or even my smaller Sig P938, have more surface area to grip on the slide.
