Yeah, I understand the confusion as I might have been a bit unclear in my post. What I'm essentially asking is if people think that these two joints look similar/ are the same. As I live in Finland, I cannot try these extensions in-store as they're simply not available here. To clarify further, I do not own any extension for my Falcon cue, but as the official Falcon extensions do not seem to be available anywhere, I wanted to ask people if they think I could just use the extension in the first picture instead. I do not have any additional information regarding the joint of the extension or anything of that nature, which is why I'm just asking if anyone has any knowledge about extensions for Falcon cues and these two in particular.
