HK mp5sd

Schalldämpfer. This German word is the only differentiation given to the 'silent' cousin of the world's most popular submachine gun. Literally translated as "Sound Dampened," the MP5SD has a large number of fans all over the world, as well as detractors. "Silencers" as they are commonly called, both in legal definitions for their regulation by the National Firearms Act of 1934, and in popular vernacular do not actually do what their name suggests. Sound suppressed or even dampened is a much better way to describe what actually occurs when a firearm is discharged with one on the muzzle. But they are, with the exception of .22 caliber suppressed guns, far from silent. Key to the uniqueness of the SD suppressor is that it is coupled with a barrel that has 30 2.5 mm ports in it to drop supersonic bullets to subsonic velocity for even greater noise reduction. It is often confused, but shooting subsonic bullets in an MP5SD is a definite no-no for what is described in ballistic performance as the world's most expensive .380. The average reduction in velocity is 200 feet per second. You can thus see why subsonic is not a good idea, apart from the unreliability that you are introducing the gun as well. Supersonic always for the SD, but subsonic is in order for all the other muzzle mounted suppressors marketed by or manufactured for, HK submachine guns.

Reno, Nevada tactical officer with MP5SD5. The '5' refers to the fixed stock combined with three shot burst trigger group. The SD series is the only series that does not use the 'A' before the version number. Incorrect would be MP5SDA5.
It is a good picture, but again stance is bladed, not current technique being taught by HK International Training Division. In pointing things like this out, I do not wish to sound critical of the officer or anyone that the photos catch doing it. I merely wish to educate the reader on the subtleties of proper technique.

but 60 rounds makes the gun quite heavy. SDs are also very muzzle heavy because of the suppressor.

The MP5SD is a sought after piece among American Class III firearms collectors. The gun is currently in the $12000-14000 range, with two $200 tax stamps being necessary for the gun and removable suppressor. This of course refers to transferable conversions, just like non- suppressed conversions of the HK94. American law enforcement agencies will pay in the area of $1900 for an SD.

MP5SD prototype. The SD project began in 1974. Many of the 'waffle' type magazines like the one shown here are marked with 'SD' on them. The straight 30 round magazines are reliable with ball ammunition, but reportedly were less than perfect with modern hollowpoints. Thus the design change to curved.
