[hwtyger]

Did a search on the Chameleon, looks like there are several model. 1 to 5?
Whats the difference between the models?

I had a 96, single and 5 shot, I still have a 97 in .22. As I remember the two pistols were look alikes, apart from the calibre, of course. Both are very accurate. Because of the CO2 cold soak, the 96 needed 3-5 seconds between shots to catch up on temperature. I thought about making another handgrip for the 96 with a heater element built in.
Another thing, the B96 bore no reference to "Chameleon" wheras the B97 bears Chameleon Mod. 5.
