When I bought my semi-auto new, it was a trick to rack. After some use, between breaking it in and my left hand getting stronger, it got easier. I just tried it out of curiosity because I have some issues with my left hand and was still able to rack without any problem.
In general, though, I do have some problems with racking different guns. My hands aren’t nearly as strong as men’s.
My wife isn’t able to rack the slide on any of my semi-autos. Not compacts or full sized. Finally settled on a light-weight .357 mag revolver, but only load it with 38 spl. I did try it with full .357 loads and it was a handful for me.
Place the firearm in your strong hand pointed in a safe direction.
Grasp the slide with your weak hand firmly.
Now, here's the important part. DO NOT attempt to pull the slide back at all. Rather, PUSH the firearm forward with your strong hand while holding the slide in place with your weak hand. Put your hips into if you need to.
Once the slide has travelled fully to the rear, release it.
I think if you'll try this method of charging a semi-auto, you'll find that it works well.
Practice with an empty firearm until you can do it from muscle memory.
I hope you find my advice useful.
Best.
