I've had a couple. They're good guns, look nice and are very accurate. The single action is good and the double is adequate. You do have to remove a plastic cover to access the hammer for single though, which does rather detract from the looks!

Also, this is the only Twinmaster CO2 that can't be changed to HPA at a later date.
if its being compared to the usual CO2 multi shot pistols its in a different league, if its for 10m I'd look again.
