Stein & Wasserman Bi-Power Handcannon

Stein & Wasserman Bi-Power Handcannon is Pistol Revolver/Autoloader. After a long wait, Stein & Wasserman's "Bi-Power'' is now commercially available! Following a previously unheard-of design philosophy, this hybrid handgun mates a double-action .44 Magnum revolver to a .45 ACP autoloader. The sturdy grip holds 13 rounds of .45-caliber ammo in a double-column magazine, feeding into the upper portion of the gun. The automatic's long slide ends in a compensator, but (because it's built into the frame beneath the barrel of the automatic and ahead of the trigger assembly) the revolver's barrel is somewhat snubby. "R" (revolver) mode or "A" (automatic) mode can be selected at the flip of a thumb-switch. Although many complain that the choice of brass-cased ammo for both barrels makes the weapon less reliable, the Bi-Power rarely malfunctions. The Bi-Power's worst problem is its size-packing a .45 auto with an 22cm barrel and a .44 Magnum wheelgun into one package makes this handcannon "L" concealability for anyone with a BOD of less than 8.
