I haven't heard anything about the 'Thunder Five' in a while. It was likely available when that movie was made. Still available, according to their site, at $560 - inc s/h - to your ffl. It is all steel now - with a 'grey phosphate' finish - weighs 3 lbs - and holds five .45 Colts or up to 3" .410 shot shells. I don't know how the action is - or whether it is SAAMI-spec's only on the .45 Colt, like the Taurus #4410 'Judge'. BTW, that Taurus is sized for 2.5" .410's - they'll have a new model - #4510 - reportedly by the end of the year with 3" chambers. Interesting firearms, but I'll keep my S&W 625MG in .45 Colt.
BFR only makes a .45 Colt in the long cylinder .410/.45 Colt format - a bit bigger still - and more moola, although it is SA only.
