The inflammation in my hands has gotten worse with arthritis making it more difficult to rack my 43x so I ordered this NDZ slide racker assist. It's made of aluminum and seems to be well constructed. I know that it simply replaces the back cap on my 43x. When I do to install it I have no problem depressing the plastic sheath around the striker, but when it comes to going over the extractor depresser plunger I cannnot figure out how to push that down to slide the slide racker over it. I can get the plunger depressed, but the contruction of the assist hasn't allowed me to slide the assist over the plunger. I've tried to push it with a punch, get under the racker with a thin screw driver and just wrestled with it to no avail.
What's t trick to this final stage of the installation?
