HK SP \u2013 Lasting Impressions<\/h2>\n

By Shane Oswald<\/strong><\/p>\n

The mark of a good design is often considered to be a recognizable silhouette. This
\nsuggests that the unique shapes and angles have become ubiquitous and culturally significant.
\nOften, there will be copies that ride the coattails of the original, trying to share in some of the
\nsuccess. This is no different in the world of firearms. It does not take a gun enthusiast to
\nrecognize the outline of a Heckler and Koch MP5. Since its first adoption in 1966, the MP5 has
\nbecome prolific among police agencies, counter terrorist organizations, and militaries around the
\nworld. This gun has redefined the role of the submachine gun and earned its place as a cultural
\nicon. Almost 60 years after entering the market, it is still considered the gold standard in its
\nindustry due to its exceptional accuracy and minimal recoil impulse. Today, it is available for the
\ncivilian population in the form of the SP5, a faithful semi-auto clone being produced by H&K
\nthemselves.<\/p>\n

The MP5 would truly come into the spotlight in 1980 when it was used to great effect
\nduring the siege of the Iranian Embassy. After the hostile takeover and execution of one
\nhostage, the British Special Air Service would be called into action. Famous pictures would
\nemerge of SAS operators repelling down into windows, MP5 in one hand. Equipped with early
\nweapon mounted lights and lasers, the SAS would successfully save twenty-four out of the
\nremaining twenty-five hostages. In only seventeen minutes, the team managed to capture one
\nIranian gunman and eliminate the other five. This impressive show of force was deemed
\nOperation Nimrod, and it would bring both the SAS and the MP5 into public view.
\nTo understand what sets the MP5 apart from the rest, it is first necessary to understand
\nthe history. The first adoption of submachine guns was in WW1, but this was only in relatively
\nsmall numbers. The guns of this era were generally heavy and expensive due to intricate
\nmachining. They often more closely resembled rifles rather than a distinct class of their own.
\nDuring the Second World War, it became obvious that something cheaper and less
\ncumbersome was required. A paradigm shift occurred, and much of the submachine gun
\nproduction shifted to cheaper manufacturing practices. This new class of smaller and handier
\nguns was generally made out of stamped sheet metal parts and welded together. This allowed
\nfor much needed cost savings and put more guns in the hands of soldiers, but many of the
\nquality of life features also disappeared. To simplify the mechanism, a vast majority of the guns
\nwould be \u201copen bolt,\u201d meaning the bolt of the firearm stays locked to the rear, and pulling the
\ntrigger both releases the bolt and fires the gun. While this does reduce the complexity of the
\nfiring mechanism, it can also result in poor accuracy, ingress of dirt and debris, and even a
\npotentially unsafe firearm. Regardless, this became the standard for submachine guns for years
\nto come.<\/p>\n

The firearm to break the mold of cheap open bolt sub-guns was, of course, the MP5. It
\nwould seamlessly blend the fine machining of early submachine guns with the compact and
\nlightweight properties of the later generation. Utilizing stamped steel and polymer where
\npossible, and intricate durable parts where necessary, H&K managed to develop a handy and
\nexceptionally accurate firearm. Its highly controllable full auto coupled with the ability to fire
\nprecise semi automatic shots made it a natural choice for professionals around the world.
\nAlthough there had been other closed bolt submachine guns, most of those were \u201cblowback\u201d
\noperated. Blowback guns utilize the mass of the bolt and the resistance of springs to slow down
\nthe cycling action. While this is cheap and simple, firing these guns tends to be a bit jarring. The
\nMP5 would instead employ a roller-delayed system. Upon firing, two rollers are forced to retract into the bolt head before the bolt body can start its rearward cycle. This mechanical delay allows
\nfor a lighter reciprocating mass that does not impact the rear of the receiver at such a high
\nvelocity. In short, the result is an extremely pleasant shooting experience.<\/p>\n

Despite the availability of more modern offerings, the MP5 remains in service today and
\nlikely will be around for years to come. It could be argued that the MP5 ushered in the new
\ngeneration of modern sub machine guns. Today, several companies offer closed bolt, high
\nquality and compact SMG platforms. Guns like the Sig MPX, B&T APC9 and the new Springfield
\nKuna come to mind. Additionally, companies such as Zenith, Century Arms, and PTR have tried
\ntheir hands at producing MP5 clones. While they may get close, they cannot compete with a
\ngenuine H&K. The civilian-oriented H&K SP5 maintains the same build quality as the true MP5.
\nIt retains all of the iconic features, lacking only in the ability to use fully automatic fire. The SP5
\ncan also be retrofitted with accessory rails to bring it into the modern age. The addition of a red
\ndot, light and foregrip turns the SP5 into an extremely viable modern platform that would make
\nthe SAS operators of the \u201880s blush. The only thing that might be considered outdated is the
\nloading doctrine, which features the infamous \u201cHK slap.\u201d This involves locking the bolt open with
\nthe cocking handle, inserting a fresh magazine, and slapping the handle down to drop the bolt.
\nWhile this might not be as fast as a modern bolt release, nobody could deny that it is downright
\ncool.<\/p>\n

Personal Story<\/strong><\/p>\n

I am proud to say that my first experience with an MP5 is also my first experience with
\nfirearms. It was no doubt the gun that got me hooked and sent me on the path that I am on
\ntoday. It all started with an unexpected snow day when I was in the 4th grade. My mom had a
\nhair appointment so I was with my dad for the day. Since I was an unplanned addition to his
\nschedule, we had to go to the police department to drop something off. At the time, he was a
\nCaptain in the narcotics unit. After stopping by the office, he still needed something to keep me
\nbusy for the rest of the day. Naturally, we headed to the armory and I got to handle some of the
\nimpressive firearms. Most other police departments would not have M14s, M4 carbines, and .50
\ncaliber anti-material rifles to show off. At the time, some members of the SWAT team were
\npracticing in the small, underground range. Formally a member of the SWAT team, my dad
\nasked if I could come in and watch.<\/p>\n

One thing led to another, and soon enough I was strapped into a three-point sling with a
\nfull auto MP5SD in my hands. What I remember best was the insane controllability. I could keep
\nthe sights on target and chug away in full auto, creating a tight pattern \u2013 for a nine year old, at
\nleast. It was far easier than I anticipated, but it turns out I was just being spoiled by German
\ningenuity. The M4 carbine and later, the Thompson (why did they have a Thompson?) would
\nprove to be far more difficult to control. The other thing that stuck with me was just how quiet the
\ngun was. In fact, at one point we even fired the gun without hearing protection. It was
\nsurprisingly comfortable, even in the confined space of the indoor range. What I did not know at
\nthe time was that the MP5SD has a clever gas-venting system that reduces the velocity of any
\nammo type to subsonic levels, thus preventing the supersonic boom. It also has an integral
\nsuppressor which sleeves over the entire barrel, giving the gasses plenty of room to expand and
\ndissipate. All I knew was that the MP5SD felt the way guns looked in the movies, and to me,
\nthat was awesome. Still to this day, nothing has lived up to that first shooting experience.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":5514,"featured_media":188833,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[553],"tags":[],"class_list":["post-188832","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-professor_shane"],"yoast_head":"\nH&K SP5 Lasting Impressions -
