    Perhaps the most common host firearms for .460 Rowland cartridge conversions are the 1911s and Glocks. However, 460 Rowland LLC constantly expands their line of conversions, introducing the .460 Rowland cartridge to more weapon systems originally chambered in .45 ACP.

    In this article, we’ll take a brief look at the latest offering of this company – the .460 Rowland conversion options for the Heckler & Koch USP Tactical pistol.

    If you are not aware of the .460 Rowland cartridge, let me briefly describe it. The .460 Rowland is a .452 caliber cartridge that has the same overall length as the .45 ACP (making it possible to fit into standard magazines and grips) however, it operates at much higher pressures (40K psi, about twice as than the .45 ACP) making it a much more powerful cartridge. In fact, the company advertises it to provide .44 Magnum power in a semi-auto pistol package. This cartridge is capable of throwing the 185-grain pills at a muzzle velocity of 1,600 fps or accelerating the 230-grain projectiles to about 1,300 fps. In order to prevent the possibility of accidental chambering the .460 Rowland into a .45 ACP chamber, the Rowland case is designed to be 1/16 longer than the .45 ACP case.

    If you browse the company’s website, you’ll see that all of the .460 Rowland converted handguns either have ported barrels or compensators. The H&K USP Tactical conversion is no exception. The muzzle brake is a must for such a powerful cartridge. The converted USP Tactical pistol comes with a match grade stainless steel barrel with the new caliber engraved on it. The barrel has a metric M16x1 muzzle thread pitch and comes with the company’s Multi-Port compensator installed. The converted handgun also comes with a new recoil spring tuned to work with the increased speed and power of reciprocating parts and designed to mitigate the recoil, too.

    The MSRP of the .460 Rowland converted H&K USP Tactical handgun is $1,557. You can also send your USP Tactical barrel and for $236 they will rechamber it for the new caliber and also send you a muzzle brake with your barrel.
