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.

Say, you know, now that you point it out, that’s just how I do it with the 9mm. I’ll have to try that with the other handguns. Possibly the shotgun, too. That one is a trick. Thank you, appreciate the advice.
