There is a problem. We can list all kinds of pro and cons about these pistols, but they all do the job well.
We who are providing guidance are not you. Trying to cover all the pros,cons, objective, and subjective material is not going to help since we can not know which will and will not work exclusively for you. Try and handle or fire as many types presented here as you can.
Moral,common sense, and ethical reasons say the gun has to fit you and that you will become proficient with it.
For instance, I have short stubby fingers. The Kahr K9 and S&W 908, new, guns were out of my price range. I went with a Makarov.
This is in part why I like revolvers. Easy to find or change grips to make sure they fit. Can be done with some pistol makes and models, but not all.
Ruger P series P95s and P97 pistols fit me though they are supposed to be to blocky. Couldn't get the other double stack pistols to give a proper fit. Not at the time.
Wanted somthing for CCW carry this state was supposed to get. Only the Taurus PT111 fit me. The others were too much of a compromise in feel or fit.
Just one of those things, personal choice, and personal fit.
There is enough difference in the regular 9mm. , 9x18, and the .380ACP to consider. What's your tolerance and ability to handle recoil? With any of these pistols learned techniques can take care of that, but that has to be considered.
Maybe the Bersa in .380 is all you need or want.
The 3.5 inch barreled pistols such as the S&W and Kahr K9 split the ballisitic difference between the compact hideaways and the full service pistols. These do it better than the shorty 3in. barreled ones. Not by much, but the advantage is there.
Pistol barrels are measured in such a way that part of the cartridge is in the area that is included in the barrel measurement. This means there isn't 3 inches of actual barrel for the bullet to travel down to get velocity or leave the barrel.
Slightly over 2 inches or less. Less actual barrel. Less actual ballistics. Less need for reliance on a +P cartridges, if actually needed to begin with.
There youhave it.
