Mercenary Guns

A mercenary is typically thought of as a soldier-for-hire by entities other than his or her own country’s military. When seeking out a mercenary-like job, a common question asked on job applications is what type of guns the individual is either familiar with or qualified to shoot. Although most private security companies will provide proficiency and advanced weapons handling training, there is an expectation of a basic-level of firearms familiarity with common mercenary guns by the job applicant. These include various 9mm or equivalent handguns such as the Glock 9mm, rifles such as the M-4, M-16, and AK-47, and various other large caliber weapons.

Mercenary Handguns

When seeking employment as a private security contractor, proficiency in one or more handgun types is a must for the majority of companies. The reasons vary depending on the nature of the job the person will be filling; however, when taking a job where one can be part of a personal protective detail the use of a concealed handgun is a requirement for most armed security details.

The HK 45 improvements include changeable grip panels, better ergonomics, more ambidextrous controls, and a Picatinny MIL-STD-1913 accessory rail. The pistol (along with the popular HK45 Compact) was produced as a potential candidate for use by the U.S. military as a successor to the 9MM M9; however, the programs looking at a successor to the M9 were suspended before a replacement was selected.

The HK45 makes use of a proprietary O-ring barrel to ensure a very precise barrel-to-slide lookup and maximizes the accuracy of the weapon. The HK45 models are able to be fitted with a threaded barrel to use with sound suppressors and are capable of firing a .45 ACP ball through +P ammo. Designed for personal defense, the HK45 is able to be converted to use a variety of trigger firing modes to include double action only (DA) or double action/single action (DA/SA).

RPK (Kalashnikov hand-held machine gun)

The RPK, also known as the Kalashnikov hand-held machine gun, is a 7.62x39mm light machine gun originally designed by Mikhail Kalashnikov for


the Soviets in the 1950s. The gun was produced in parallel with the AKM assault rifle and was first created to replace the 7.62x39mm RPD light machine gun. Despite its age, the RPK continues to be used by a number of African, Asian, and former Soviet Union countries today. The rifle was also manufactured in Poland, Bulgaria, and Romania and functions identically to the AK-47 using the same ammunition. The rifle has had modifications to help increase its accuracy, effective range, and sustained fire capability.

Other features of the RPK include having a longer and heavier barrel than the AKM allowing it to conduct sustained fire for longer periods of time than the AK-47. The barrel of the rifle is permanently fixed to the weapon’s receiver and is not designed for field replacement. Other features of the RPK include a front sight base, under-barrel cleaning rod guide, folding bipod mounted near the muzzle, and a front sight base with lug. The muzzle of the gun is threaded which allows it to be used with compensators, blank firing adapters, and flash hiders.
