A lot of women have difficulty pulling back the slide of a center fire semi-auto.
No, they just haven't been taught proper procedure. Just like putting a motorcycle onto a centerstand, it's all about technique, not strength.
Technique is important, but it can't overcome lack of strength in all cases.
There comes a point in life when a person loses strength, and I'm there, and I guarantee I know how to operate a pistol. I'm at an age where I associate with a lot of older folks and it is a universal problem, more so with the ladies.
