In the old days, Triad wars featured more traditional weapons.
Recently the police in Taiwan captured a more modern, but equally unusual, example of Triadic weaponry. EDNDO Gun Blog:
(bad Google translation from Chinese, edited by me)
Police said 19-year-old gang member So and So was apprehended for violation of weapon-carry laws resulting in the search and seizure of an arsenal housed on the 7th Floor of Linsen North Road, Suite A. A revolver and 6 rounds of canister-style shotgun ammunition, as well as four pistols, one a standard Beretta, the other three improvised firearms, along with 15 bullets and 19 blank cartridges.
This is the very large shotgun revolver, can be loaded with 6 rounds. The frame is of steel construction. With a short barrel, it weighs more than 3 kilograms (6 lbs, 10 oz.). There is no rifling, but there is a base intended for a sight. There is no guard on the exposed trigger, and so safety, so when fully loaded, if the trigger were to pulled intentionally or by mistake, the weapon will fire, which is very dangerous.
The incongruous home-made Beretta logo and the “Made in USA” must both be decorative efforts to add logos to make the piece look more like a factory manufactured weapon.

I suppose Triad members in Taiwan must have importing issues, but nearly 7 pounds worth of revolver is a lot to carry, and the recoil from a 12 gauge revolver must be awfully unpleasant. Taurus actually produces a series of revolvers chambered for both .45 Long Colt/.410 Shotshell representing a considerably more practical application of the same idea.
