Yeah, but it's not the same as the Panthera. No safety screw. I'm sure someone will try to fit one in a panthera at some point. Maybe the match for the pro.
Depending on where you live, that can be difficult to get. Definitely not at the pump in CA. You have to get race gas. F&L Pure 93 runs me about $48 for a 5 gallon can and that's all I use for my equipment.
