45automan,
I have fired all the 9mm's you mentioned, and I own a P95. I too had the same challenge of finding an appropriate weapon for my wife. Essentially, if someone is not used to guns, anything over a .22 is going to feel like a violent eruption in their hands. Guns go boom -- it's just what they do.
Fortunately, almost all popular calibers of handguns today are manageable (and most are enjoyable) provided the shooter take the correct approach and technique. By correct approach, I mean that they have to understand what is to be expected by shooting a combat-caliber handgun. Technique pertains to grip (a world of variables there), stance, trigger press, sighting methods, etc.
If your wife needs some convincing that she is truly capable of effectively using a major caliber handgun (approximately 9mm and up), check out this link:

While physical differences between men and women make for a few considerations for caliber (read: recoil), it shouldn't be assumed or concluded that a woman must have a less-potent caliber for manageability concerns. I believe men and women alike can be trained to be an effective shooter of most popular cartidges.
In addition, I have to add my opinion that you shouldn't search too hard for the perfect-shooting 9mm. In my experience, I haven't found too many all-out miserable 9mm's to shoot (not counting good/bad trigger-pull attributes). While some 9mm's are definately works of art and prime examples of fine weaponry engineering, the majority of 9mm pistols from reputable brands will be comparable in the shootability department.
So to sum up my point in this epistle
(I always get carried away), you have to find some way of gently conveying to your wife that part of the "kick" she experiences she'll just have to deal with, and that through use of proper shooting form, she can shoot a 9mm very well, independent of the particular model of weapon.
That said, I'll throw in the stock answer: whatever she shoots well, go with it. Though I wholeheartedly believe that if she has resolved to make available a handgun for self defense, half the battle is over and it should just be a short stride more to really hone in on the right weapon. For my wife, we settled on a .38 snubbie w/ concealed hammer (a pre-agreement S&W 642). While not a "honey" to shoot, it is a great purse gun, and she prefers its simplicity to semiautomatic mechanics. One day I hope to "upgrade" her to something with more capacity, power, and shootability, but 'til then I'll be glad she at least has a formidable weapon with which to defend herself when I am unable.
Don't give up on the likes of Ruger P95, Sig 225 (great deals on them these days) 228/229/239, Glock 17/19/26, Kahr, Beretta (it's a big one
), and the list goes on. Keep her shootin'!!!
Best wishes in your search.
