Here’s the things I notice - keeping in mind these are generalization and not always gender-linked:
I tend to need to correct men more on trigger discipline, and women (once they get that’s where the BANG is) a lot less.
Women have a lot more trouble with limp-wrist. teaching them to push forward strong hand and pull back weak hand to create a little isometric tension really helps with this.
Men are more likely to want to move up to a bigger caliber before they’re ready (meaning: safe and accurate.)
Women are more likely to fatigue and lose accuracy faster if keeping the firearm at full extension than men are. If I see that, I have them go to low-ready more often while they build up stamina.
Women are far more likely to be leaning back and to continue to return to this posture after many corrections - there’s a reason for this that I think most male instructors miss. Women, in general, don’t have the upper body strength that men do. Put a firearm at arms length forward and ask us to hold it up for a period of time and we’re going to offset the weight to closer to our center of gravity by moving our upper body back behind the centerline. It’s the same thing we do when carrying a kid on our hip - we shift the upper body away from the weight. Once I see that’s what’s happening, explaining it to the shooter, rather than just correcting them over and over, solves it much more quickly.
