How are you racking the slide? A very common problem...I have found that the most effective way to handle that problem is to get both hands involved in running the slide...(this assumes you are right handed) Holding your handgun in front of you...pointing to the left...Gripping the slide over the top with your left hand...now push to the right with your left hand and push to the left with your right hand. Once the slide is fully open...let Go! Don't ride the slide!

One method I have used with folks that seems to work with just about everyone. Regardless of which method you use instead of trying to pull the slide back try “punching” the gun through your hand that’s holding the slide.
This gets the chest muscles involved and they tend to be stronger than whatever muscles you are using to pull and requires less weak hand strength to accomplish.
