Rotator cuff issues can also cause great difficulty in racking a slide. Arthritis can also be an issue along with grip strength. The best method is indeed one hand pushes and the other pulls.

I have a harder time putting the last round in the magazine of my Glock 19 than I do racking the slide. Another reason for the Uplula mag loader.

Other than working on his technique/strength, Try sticking some grip tape on the rear of the slide first.
