I have a factory SD. Yeah it WAS cool for a couple months. But in a practical sense, it only has one use. CQB.
But they don’t do anything great. A std 16” 5.56mm AR15 is far superior. Even a pistol AR15 is superior. Anyone who would pass by an AR15 to grab a MP5 in an emergency situation is an idiot. |

The cyclic rate on the K is too fast to really be useful past about 15 yards. It can dump a lot of rounds fast though.

If you are shooting suppressed or with really heavy ammo you need an 80 degree locking piece vs the 100 or 110. |

H&K recommends swapping to an 80 degree locking piece if shooting suppressed. From what I understand, the increased back pressure can cause premature wear unless you switch the locking piece, which will slow down the unlocking. Also recommended if you’re shooting 147gr out of the K. Since most people running suppressed are shooting 147gr as well, I would absolutely swap the locking piece in a K. |

If you really want an SD get the SD. If I were to pick up one again. And only have the one. I would probably get the K and pdw it with the folding stock, grip, & suppressor. |

Yeah that’s the whole point. I don’t really need to watch a video to know 9mm is less than ideal for killing stuff. The 300 blk does everything better than 9mm except weigh less. Hence the LVAW program. There’s still a place for a gun somewhere between a Glock 9mm and a 16 in 5.56 even if you don’t have a use for it. And if it’s going to suck ballistically either way I’d at least prefer it to be able to take supers, subs, and have some range beyond 100 meters. |

It almost looks like a steady stream of brass pissing out of the ejection port. I guess I probably shoot the full size the most often, but the K probably maintains a much higher round count. At least it did back when I could afford to feed it. |

I have both. MKEs are cheap. Buy both.
But if you absolutely insist on "only one", define your use case. The full size is more enjoyable to shoot. If you're looking for a fun range toy or something for the wife and kids to enjoy, full size with A2 stock all day every day. If you're looking for a gun thats concealable but more capable than a pistol for scenarios like 2020s summer of mostly peaceful protesting, the K with a B&T collapsable stock. The old school choate PDW look is iconic, but thicc as hell. The K with the B&T stock is a damned handy package that is easy to conceal but way easier to shoot well than a handgun. Pick how you're going to use it and buy one accordingly. Or man up and buy both.

Also recommended if you’re shooting 147gr out of the K. Since most people running suppressed are shooting 147gr as well, I would absolutely swap the locking piece in a K. I was lucky enough that my "K-PDW" runs just fine with no can and the #28 80 degree locking piece. That's the way I left it 100%. IF the rifle will run all the time the 80 degree will slow down/smooth out the cycling and it'll be much more behaved with the can. |

Quote HistoryQuoted: For the first, full size. Get the K second. Yes I know you said only one. Two is one. One is none. And realistically at current prices you can buy two for the price of one last year. Pretty much this. As a general rule, the full size is going to do just about everything you need/want. No with that said, the K gun is good if you need something really small and compact. It's great for a pistol caliber carbine if you are committed to the MP5 line. I got my K gun first because I was looking for something that would fold up, host a can, and be easy to get in and out of a vehicle. I got the full size next, and I shoot it way more and keep it out more around the house. Zero regrets about either one, but the full size sees more time out of the safe. |

Quote HistoryQuoted: Yea whatever First we have to assume the steel and heat treat are as good as the German guns. Next the Action 3 is a real advancement especially the ejector but for longer term durability the action 3 bolt changes extended the life 60%. These MKE former HK contract guns offer a great value and I think 90% are good guns but they are absolutely not HK quality. Too many misaligned triple frames, older spec parts and softer steels. For reference: It looks like US navy demands in the 80's that predated the action 3 bolt led to the improvement that gave 60% increased life to the bolt. I believe that change would be in the MKE design but photos could clear that up. https://www.hkpro.com/threads/difference-between-mp5-mp5k-sp89-action-3-f-regular-bolt-head.148657/#post-1375342 |
