I bought some rubber CZ base pads from Greg Cote LLC. They look like authentic CZ. I thought it would be really simple to install them on the CZ magazines - I just slip them over the existing metal base plate, right? It's a very tight fit so I aborted and am now researching. Nothing on YouTube. Upon a search of this forum, I could only find a 10-year-old thread where the OP wrote that he used a mallet. Does that sound right?
