In case you've missed it, Daiki Kougyo recently released a water gun iteration of Captain Harlock's Cosmo Dragoon. It goes for a little under ¥3,000 in Japan but I'm already seeing EBay listings going 2-3x that.
Ah, well, that's a bummer. At any rate Rgriesbeck's kit fits perfectly well around the airsoft J-frame I'm building so it suits my needs well enough. The Takagi water gun was just too big profile wise.
edit: here's Rgriesbeck's cast grip for his printed kit and the water gun. Grid is in cm.
Not sure about it being too small but it is roughly 10% smaller than the Takagi water blaster. I believe he mentioned scaling it after a Tomenosuke so should be more or less spot on.
The water gun is molded from an old Takagi which is slightly larger than the real one particularly with the grips. I'd suggest a printed kit by Rgriesbeck and he can (depending on availability) supply you with cast urethane grips for them.
Those look really good. One thing though: none of those (Glock, Shield) are supposed to be blued. It's a shame to get such crisp detail on it but the blued finish really puts it off.
Not that I know of. As far as the original blaster was concerned Ridley Scott allegedly walked into the prop house, pointed at the Steyr and said it looked cool so on it went. The only explanations I've come across with the new blasters is they're stylized after the original in that they had the...
K and Luv's guns were non-firing. The trigger merely actuates a solenoid working some kind of hammer/striker device on top for aesthetics and visual cue for post prod sfx.
That makes things more convenient as a prop I guess, but still far from something desirable to be used defensively if that were how things work canonically.
I've used those brazing rods for aluminum and work extremely well for pressure/weight bearing parts. But if the surface area is large enough, steel filled epoxy or industrial cyanoacrylate works well too. Just roughen the surfaces to be joined with sandpaper and don't wait too long before...
I can name a few. From old westerns from the 50s to recent action flicks. But more often than not they pay more attention to weapons with a lower capacity. Modern handguns hold so many you can easily lose count even on a real one.
Case expansion happens to all brass cased ammunition, not just revolvers.
As to the "negative flash", I believe that only applied to the original concept art "black hole gun". Ditched for impracticality and lackluster SFX, they went with some energy based weapon instead and why target impacts...
