The UMP is a cost-effective, state-of-the-art submachine gun that offers users the advantages of light weight, low initial purchase and maintenance costs, uncompromising reliability, and precision accuracy with low felt recoil.
The UMP is available in .45 ACP and .40 S&W variants.
The UMP45 provides the user with a magazine capacity of 25 rounds* with an accurate range of 100 yards or more, well beyond that of any issue handgun or shotgun. Due to its small size (less than 18 inches with the buttstock folded) and 41/2 pound unloaded weight, the UMP is the perfect choice for use in or around vehicles. Its size and low weight also make it the ideal weapon for smaller stature officers who have difficulty handling the size, weight, and excessive felt recoil of a full size rifle or shotgun.
The UMP45 is designed and tested to fire all types of .45 ACP ammunition—including subsonic and supersonic loads, cartridges assembled with ball, high performance hollowpoint projectiles, and even enhanced velocity +P offerings. The UMP45 also fires nontoxic and frangible training ammunition without modification.
For familiarity of training, the UMP offers fully ambidextrous operating controls and sling attachment points similar to those found on other HK rifles and submachine guns. A convenient bolt catch holds the bolt open when the last round is fired and along with the flared magazine well makes for quick and easy reloads.
Hard points molded into the polymer receiver of the weapon allow for the attachment of a wide assortment of optional mounting rails and accessories, such as assault sights, tactical lights, and vertical foregrips.
Additional standard features include fully adjustable iron sights with a dual flip-up rear aperture, an HK multipurpose tactical carrying sling, and a detachable vertical handstop. Optional tritium sights are also available.
UMP firing mode choices include semiautomatic only, semiautomatic and 2-round burst, or semiautomatic and fully automatic modes of fire.
With the exception of the barrel, bolt, and certain internal component parts, the UMP45 is constructed entirely from tough, lightweight glass-fiber reinforced polymer. The UMP magazines, also made of high strength polymer, feature a transparent ammunition-viewing strip that allows the user to see the type and quantity of ammunition inside.
The sturdy UMP folding buttstock has a rubber cheek piece and buttpad and reduces the overall length of the weapon by nearly ten inches when closed.
Like all HK submachine guns, the UMP fires from the closed bolt position to improve accuracy and enhance safety when handling the weapon. A passive internal firing pin block within the bolt prevents the weapon from firing if dropped.
The MP5SF (single fire) carbine is a semiautomatic only variant of the MP5 fitted with a trigger group that prevents full automatic firing. The Single Fire (SF) trigger group can be replaced with other MP5 trigger groups to allow burst and full automatic firing.
The MP5 Single Fire is an ideal squad car carbine. It is an excellent supplement or replacement for a police shotgun. It has less recoil, greater range, and more ammunition capacity than a shotgun and is especially suitable for small stature officers.
Heckler & Koch MP5 submachine guns employ the same delayed blowback operated roller-locked bolt system found in the famous HK G3 Automatic Rifle. All the elements of HK excellence; reliability, ease of handling, simple maintenance, and safety are highlighted on the MP5. Firing from the closed-bolt position during all modes of fire makes MP5 submachine guns extremely accurate and controllable.
Used by military and law enforcement units in more than fifty nations, the MP5 is firmly established as the world’s preeminent submachine gun. Over 120 variants of the HK MP5 submachine gun are available to address the widest range of tactical requirements. A selection of optional trigger groups allow for single fire only, full automatic, 2-round, and 3-round burst options. The weapon’s unique modular design and a variety of optional buttstocks, forearms, sight mounts, and other accessories gives the MP5 extraordinary flexibility to meet most any mission requirement.
