Okay…time for a side by side comparo…
LDT vs JM…!!
Ding Ding, round 1!!
Honestly, JM have done a pretty good job, with the MP5-K.
The shell quality is good, much better than their mp5’s of several years ago, details and decals are good. LDT has the upper hand though.
Heavier grip and lower receiver, when you pick up the LDT, it feels heftier and sturdier in the hand, like your holding a real one. Dont get me wrong , the JM is good, but LDT ‘feels’ a bit better. The grade of plastic is a bit better and darker on the LDT, though this is minor, and only picked up when side by side.
A point for some, with the LDT, you can remove the tri-lug, for the ultra Compact look. With the JM, the inner barrel goes all the way to the end of the tri-lug, so you would have to cut the inner barrel back, for the Compact look.
Performance wise, i got very similar figures for both, through my chrono. Both around 1000-1100 r/min, and 180-210 fps, with a few higher and lower flyers. So, a tie on performance. The JM gearbox is quieter.
Now, the mags…
STEP 1: Physical fit.
*The LDT mag, fits easily and crisply, into the LDT with a sharp click
- The JM mag fits into the JM, with a bit of a jiggle required, and no sharp click.
- The LDT mag, fits into the JM fairly easily, with a slight click(sometimes)
- The JM mag, fits into the LDT, BUT DOES NOT LOCK IN.
STEP 2: Electrical contact.
The issue is, reversed contacts.
The LDT has protuding springs in the magwell, and recessed contacts on the mag.
The JM has recessed contacts in the magwell, and protruding terminals on the mag.
The mags do physically fit, as above, but you would need to do some terminal work, to ensure compatability. Using LDT mags (plentiful in OZ) in the JM, you would need to work on extending ( and forward angling) contacts…
Is this a maori war face mask, or a couple of bird chicks waiting to be fed.?.?
Protruding JM terminals…
Recessed LDT terminals…also slight difference of placement.
