Chambered in 4.6x30mm, the HK MP7 was designed in the ’90s specifically to defeat Kevlar body armor. With no civilian version available, the MP7 has developed a cult-like following over the years. As opportunities are few and far between to shoot these, I’ll jump at the chance to shoot an MP7 whenever possible. Lucky for me, Jake from 1911 Syndicate reached out recently about doing a video on this iconic machine pistol.

The MP7A1 (kindly provided by SK Arms) was topped off with an EOTech and the B&T MP7 QD suppressor. Overall, the setup is controllable and has an inherently HK feel in terms of controls. As you’ll see in the video, the charging handle was a little worn out, and we all received a couple smacks to the face during firing.

NOTE: The video contains some NSFW language.

In regards to any specs I might have missed or messed up, here’s the full rundown from HK. (Note: Average ammo velocity is ~2,000-2,410fps)

Specifications:
  • Caliber: 4.6 mm x 30
  • Operating principle: Gas-operated
  • Magazine capacity: 20/30/40 rounds
  • Rate of fire: approx. 950/min
  • Length min/max: approx. 415/638 mm
  • Width: approx. 51.0 mm
  • Height: approx. 169.0 mm
  • Barrel Length: approx. 180 mm
  • Sight radius: approx. 230.0 mm
  • Weapon Weight: approx. 1.90 kg
  • Magazine Weight: approx. 0.10/0.15/0.20 kg

Below is the full MP7A1 product overview from Heckler & Koch:

The MP7 represents a new generation of enhanced-performance submachine guns that bridge the gap between assault rifles and conventional submachine guns. Developed as a genuine personal defense weapon, it far exceeds the NATO requirements profile.

The MP7 is extremely compact, lightweight, can be used in very confined spaces, and is practically recoil-free. It can be carried continuously, making it the ideal personal weapon for the soldier of today. Those who carry it will be suitably armed for the broadest range of operations.

Comparing the calibres, the penetration and terminal effects of the 4.6 mm x 30 cartridge are several times those of the standardised 9 mm x 19 cartridge. By way of illustration: The new high-performance calibre penetrates the NATO CRISAT TARGET (1.6 mm titanium and 20 layers of kevlar) even at 200 m. One fundamental requirement: At the same time, the risk of overpenetration is reduced to a minimum.

    @Kivaari:disqus
    @Kivaari:disqus @Kivarii I always sensed some wisdom from your posts. Nice to read the comments of an honest man. I just past on a 5.7 AR platform that sat
    on the shelves for at least a year. It was used, but cheap and came
    with 3 extra of those fancy high capacity extra magazines. it was only
    about $700 bucks, but nobody on either side of the tri-border region
    carried ammunition for it.

    As I progressed in my career, it the standardization factor kicked in. Its something
    Americans do poorly, with regard to the to policies that impact the
    armed forces. I know longer really care about trying every new
    round, I want low cost ammunition that gets the job done target practice
    and plinking - something around the home, or CCW. 45, 9mm, 22, 556.
    Although I am thinking the 10mm is just superior out of the gate for
    pistol needs in all environments, I just don't own one.

    Recently I went against the grain for hunting elk - decided to start putting in
    for my tags. I think deer season meat isn't worth the effort or
    taking the animal based on the dislike of my taste buds. For elk I
    listened to dozens of people, some posting here, and many friends that
    hunt it with frequency in Arizona, Nevada, and Utah. I ended up
    purchasing rifles chambered in each of the most hyped rounds.

    Ended up buying 30.06, 308, 7mm, 6.5, and 300wm. Have shot 30.06 in the
    past and it kicked with some authority - a remember it as being a man's
    round. Have not test fired either of these new purchases, yet to see
    which I like best. The new plan is spending some time figuring out
    which is best for me, and either giving away as gifts or dumping the
    others.

    I finally realized from many who use
    just one trust rifle for everything, every one of the rounds I bought
    will all bring down elk - as would a .223 from what i read by avid 223
    hunters. Just seems a bit small for a 700 pound male or 500 pound
    female For me, comes down to ease of access of ammunition (or
    reloading that I may invest in) and that is the real cost to practicing
    for better shot placement, finesse with the rifle selected, an the
    optics I purchase.

    If lucky I will begin getting elk tags this year, or next year and will have about 10 years of
    enjoyment with this as a hobby to fill the freezer. Elk only ranks
    behind chicken/quail, cow, and pig that I am used too, tied in 4th place
    with Buffalo steak. For the most part, the local Walmart and other
    markets have plenty of the same and frequently on discount - dressed,
    marinated and ready. @@Kivaari:disqus

      @Guest Don't under estimate a good 9mm JHP load. A 9 runs at about 35,000 CUP, which is close to .357 Magnum. The +P+ loads are within a few FPS of .357 SIG, and that is pretty good. My service issued Glock 17 had 33,000 rounds of mostly +P+ and it was running fine. I replaced a few springs, not because they broke, just to be safe. If you do well with a .45, it's hard to beat. Our dept. issued Glock 21s (SF didn't exist) and I told the chief I couldn't shoot them due to frame size. I had to show him. They bought me a G17. After out shooting everyone else, the whole department switched to G17s or G19s. Everyone shot better, and faster. I could put 9 rounds onto the moving targets while the guys with .45s got off 3 or 4. I told the chief, I'd rather get there with less, than miss with a .45.

    The MP7 is a German "Hissy Fit" because Germany refused to accept the Belgian P90.
    Recently NATO accepted BOTH as "official" cartridges/firearms to end the stand-off.
    Let's compare the MP7/4.6 x 30 to the superior P90/5.7 x 28:
    1. the 5.7 x 28 cartridge is superior to the 4.6 x 30 per NATO tests.
    2.The P90 is TOTALLY ambidextrous and ejects spent cases DOWN - nice when firing from a vehicle and if you are left handed, not so the MP7.
    3. The 5.7 x 28 cartridge will push its heavier 40 gr. bullet farther at a supersonic speed (more lethality at a greater distance).

    Full Disclosure: I own a PS90 and have put over 800 rounds down the spout with NO malfunctions. This semi-auto sub gun is quite accurate to 100 yards and lethal to 200 yards. Also I have a RUGER 57 pistol in the same 5.7 cartridge as a "companion" to my PS90.
    (Now if i could only find some 5.7 ammo at less than $1.00 per round!)
    Lessee, I have five 50 round PS90 mags and three 20 round RUGER 57 mags. And "The Vest Guy" makes the best mag pouches for both magazines. Zombies beware - "militias" too.

      @Eric B. It really is quite silly that HK felt the need to create their own smaller round instead of just using the 5.7x28.
