Explosive Enterprises · hands-on · mixed · 5.5/10 (inferred from stance)
“Mara M9 is certified trash”

Airsoft_Chay · hands-on · mixed · 5.5/10 (inferred from stance)
“In conclusion, the Mariam MP9 does have its faults, but for the price, I think it's designed well.”
The reviewer finds the Maruyama MP9 well-designed with solid polymer and modern controls, though cold weather performance and siphoning are disappointing.
Jaeger Precision · hands-on · positive · 8/10 (inferred from stance)
“singing all the right signals”

Jaeger Precision · hands-on · positive · 8/10 (inferred from stance)
“in terms of CQB it was a bit of a monster”
The reviewer used the Maruyama MP9 at a cold CQB night and reported it performed beautifully with phenomenal accuracy and consistent FPS, suffering only one sticky valve issue and a counterintuitive trigger.
Jaeger Precision · hands-on · mixed · 5.5/10 (inferred from stance)
“Out of everything that we've looked at today, this thing is by far the biggest waste of money.”
The reviewer tests Maruyama MP9 accessories, praising the magwell and short mag but criticizing the charging handle as pathetic and noting the trigger required filing to fit properly.

Also covering it (not yet read by the index):

Tested by Ed

I ordered the Marama MP9 because I love how the MP9 feels in the hand, and out of the box this thing feels really good. The stock is solid and super comfortable, the grip angle is really comfortable, and it's so light without being front heavy. I don't like the trigger at all — it's got tons of travel and a mushy push — and the charging handle feels very cheap. It cost me around $400 plus a tariff, and I'm excited to actually play with it next week.

Problems he hit

Charging handle feels very cheap and moves around loosely · 07:33
Included suppressor would not tighten/lock down easily during install; Ed plans to thread-lock it · 10:15
Hop-up adjuster sits where the optic mounts, so the sight must be moved to adjust hop · 16:42

Out of the box

~$400 USD (Ed's estimate, plus import tariff)Price quoted

Unboxing only; no chrono or live-fire testing of the MP9. Comes with suppressor and VFC-style speed loader; ships with orange muzzle cover for US market.

Caveats

  • Unboxing only; no chrono, accuracy, or gameplay testing of the MP9 in this video
  • Power source never explicitly stated; MP9, SPC9 Pro and KWA MP9 treated as gas blowback since they share the same gas magazines
  • ~$400 price is Ed's recollection, and he also paid a US import tariff
  • Aftermarket trigger and charging-handle fitment complaints are second-hand from Jagger Precision videos, not Ed's own experience
  • Positive gameplay comments (satisfying eliminations, great CQB replica) refer to the SPC9 Pro, not the MP9
  • KS1 brand not stated in the transcript
