I just bought a slightly used SuperNova yesterday. It looks brand new. I brought it home, stripped it down, and cleaned it. I didn't get an owners manual with it. So I followed the one online. I removed the magazine cap and saw where one corner was slightly pushed in . Is this the way it comes from the factory? I couldn't get the retainer out. I didn't want to break it. What tool do I need to get the spring retainer cap out?
Thanks!!
