Here's a new report to add:

If I may Entertain you Mr. Hitman...

I'm afraid that the results are not too good. While some may argue against this, my testing and fitting yielded the following results: NOTHING FITS CORRECTLY!!!!!

These parts will fit into the Marui Glock but hinder the performance of the pistol greatly. The measurements on the WE parts are NOT 1:1 to Marui's (but what are these days!?).

-The WE loading muzzle is too "small" causing a severe hampering in gas efficiency. Often times, the gun will not cycle crisply nor will it even give a "sufficient" muzzle velocity. When I tested this set up (WE internals into a Marui BBU,Hammer assembly and hop up unit), the fluctuations in power outtage varied greatly and was hard to predict. At times, it went from one extreme of 275fps to the other extreme of 345fps in two shots. I suspect the temperature of the WE magazine has a large hand in the power outtage but the I also sense that the loading muzzle is causing most of the eratic behaviour.

-The WE Hop unit has a slight difference. It is missing the little tab that keeps the unit from "slipping off" when inside the outerbarrel. Marui Glock owners will recognize this tab. When one is seperating the hop up unit from the outer barrel, the tab will prevent it from freely dropping out. WE does not have this tab but Marui does. So when retrofitting the WE Hop up unit to the Marui outer barrel, it is uber tight. Mine had no play at all. This can be both a positive and a negative but regardless, you need a little bit of play for the outer barrel to tilt (for realism sake).

-You can't fit any Marui loading muzzle in to WE Glock because it is too large.The muzzle won't move back and fourth as it should. It will cause jams and wear out the gas route packing on the magazine. That is...if the slide can even cycle. You could modify it but you'll take away the integrity of an already high stress point of the gun.

-The WE hop up and bucking unit did not accomodate the Stock marui inner barrel accordingly. The bucking couldn't create enough backspin for the hop up to run properly.

-You can fit a Marui BBU in a WE slide but you'll get mixed results. There will be a lot of play between the lower and upper portions of the WE Glock resulting in poor and "uncontrolled fluctuations in power and gas efficiency. This misfiitting results in the dreaded "my mag is sitting too low syndrome so I need to push it up for better whatever whatever whatever..."

The Hammer assembly of the WE G18c is not to spec with a TM G18c. There was catastrophic failure in my tests wherein the semi sear didn't not even "activate". It wasn't that the slide was not getting enough blowback to keep the hammer down but the the sear wasn't actually aligning with the hammer lock at all. It was a strange diagnosis when I stumbled upon it. What made it worse was that because there was play room for the slide, the secondary full auto sear didn't release the hammer. SO i got a gun with a trigger pull but no shot....

The WE G18c also uses a rotary style hammer bearing like the G17. You won't be able to swap the WE Hammer to a Marui and use the Marui hammer bearing. It will cause problems during the cycle.

-The WE Outer barrel is a give and take. This is because it has to accomodate the locking tab found on the Marui Hop up Unit (the one mentioned above). You'll either have to modify the hop up or modify a slot on the WE outer barrel to accomodate the locking tab.

-As a minor note, the recoil springs of both guns degrade the quality of the blowback in both guns. Why this is I have no clue.....

I also tested some after market parts on the WE G17. The Guarder outer barrel doesn't fit 100%. It's uber tight. The AIP Steel hammer somewhat fixed some of the hammer issues but still has too much friction. The Guarder loading muzzle doesn't fit a WE Glock. A ninebal piston head is tight on the WE. You can imagine what it will do to the loading muzzle once the o-ring starts to expand when gas pressure is applied. lol.

Most aftermarket parts are catered to Marui specs. SO I suspect that some of them will cause problems on a WE Glock.

hope that helps.
