Go to a gun store and spend quality time in holding and dry-firing as many models as you can. Ask questions and listen to suggestions. Research like this and on other web sites is your friend, keep doing it! Everybody’s hand is different and what fits one person may not do for another. Consider your purpose for having a pistol, is for home defense or is it to carry? If you can narrow your choice down to 2 or 3, buy some firing range time with those. then you can make an educated choice! Best of luck!
Definitely home defense. If the balloon goes up. I’ll add carry.
