I ordered myself this cool bit for my WE M&P through work, along with some of the sears, hop up adjuster dials, hop up adjuster arms, and outer barrels. This is the benefit of working at/buying from a shop that deals directly with WE – I can easily source WE factory parts, including full-trademark parts… like this full trademark slide:
I guess this full trades slide would be the one that you would see on the full-trademark WE M&P if such a model (from the factory) were easily found… which it is not. I’m now definitely proud of my personal WE M&P – last finishing touches would be a steel/reinforced sear (if only someone would produce one). I’m not going to bother trying to order a trademarked frame from WE – I can live with the “WE” marking as is.
Anyway, there are a couple more photos and my thoughts in brief after the break.
Trademarks are nice and deep. (Pretend that the crooked “MADE IN TAIWAN” gold sticker isn’t there, it does come off and I’ve since removed it.) I’ve seen WE M&P’s with laser-engraved “trademarks” that look ugly in comparison to this slide (another local retailer here sold those UN Company custom-laser-engraved WE M&P’s for a bit – note that the lasered trades were not done in the WE factory), and I’m most definitely glad that I waited to get this slide instead.
Slide fits tighter on slide rails in lower. This is a definite plus, as the stock WE slide felt a little wobbly on almost all the WE M&P’s I’ve handled at work.
Note that the inside of the slide appears ground down from the factory… Likely due to casting defect (as you can see from the imperfect notch between the holes for the outer barrel and spring guide. Not the best first impression, but things get better from here.
I did also order a spare outer barrel, as the rear “leg” hanging off the barrel that interfaces with the hop up chamber broke off – not the first time I’ve seen this happen on the WE M&P. This causes the outer barrel to occasionally fail to tilt and unlock from the slide, thus preventing the slide from cycling as easily as it should.
As I’ve never had to open up the slide on my WE M&P until now, two details struck me as WE going beyond the industry standard of just making the slide mould look like there are extra parts attached to it (I know, I’m just as shocked to find this, as I’m used to WE not going to this level of detail). The dummy ejector is indeed a separate part, held in place when the blowback unit is assembled into the slide. The dummy pin on the top of the rear of the slide is a small protruding pin cast into the blowback unit.
Just so you know, the factory replacement sears are just the same sears, but pre-modified with the same method I’ve depicted previously – diagram from WE here, and my own video depicting how to do so. The new hop up adjuster dial from the factory is thinner in width, so it fits much better in the hop chamber. The new hop up adjuster arm pushes further down on the hop up bucking, allowing for greater hop up effect to be effective on BB’s heavier than 0.20g.
