Removing Cougar firing pin. HELP!

[glockorama]

I'm trying to do the home conversion of the Stoeger Cougar from an F model to G (decocker only). Step 1 is to drive the firing pin catch spring pin, that holds the firing pin and pin safety, out of the slide.
I cannot get that sucker to budge! It is a roll pin running the width of the slide.
Any help on how to remove that pin?

Roll pins are best dealt with using a special punch made for the purpose. Brownells has them.
