Really? Why's that?
Is there a type of handgun with less of a kickback? The Glock 19 isn't that bad, but it still is jolting. I'm not that strong.
9mm is your best bet then. your stance can help a little bit with controlling the weapon, as well as your grip
as for the reasons why it comes down to the shooter making simple mistakes, the first time shooting people tend to follow the basic principles better since they’re more conscious about it, then gain a sense of confidence about having such a good result the first time
then they get overconfident and don’t focus on the target properly, or jerk the trigger instead of squeezing, tensing up in anticipation of the recoil etc. that’s really the biggest killer - forgetting the basics or thinking you’re some kind of expert now
the placement of your finger on the trigger can also make a big difference for some people - the two most common and suggested being using the tip of your finger, and the other being to rest your trigger on the first joint of your finger - so basically for an easy visual the trigger resting on the first line of your index finger’s palm from the tip
when I first started shooting rifles I scored 320/350 on a practice run for a scored range and then the next day I scored 288/350
looked at my shooting book and learned I was jerking the trigger - and was shooting with scope shadow (something that only really applies to rifle scopes) and it’s all because I admittedly was too relaxed and confident about my score the past day
edit: also other things that help with the recoil of a handgun is the barrel length - obviously the longer ones will handle it a little better and can provide some better accuracy at greater distances.
the other thing being polymer vs steel - polymer guns are lighter so they can tend to kick back a little more, while steel ones are heavier and can absorb it a bit more. modern day handguns are mostly polymer however
