First time I fielded the gun i could not get it to work. It seemed like i was getting light strikes, as i was using propane and it was fairly hot. I emptied gas on mag, filled with a small amount of green gas and had the same issue. I removed the flow valve and noticed one of the o rings was completely mangled, it was almost flat like a washer. If you stand up the valve vertical with the impact portion facing up, the oring on the bottom was the bad one (the one that seals the valve). Removed and replaced with one at local hardware store and it was up and running in no time.

 

JUST FYI if you seem to be getting light strikes check your flow valve before tinkering with the hammer spring.

The flow valve on the actual magazine. I thought the valve wasn't opening due to weak hammer spring or too much pressure inside the magazine. Turns out the o ring was deformed and not allowing the valve to open freely when struck.

Great, I will check my mags and replace the o-rings. I got plenty of spares to use! Might be part of my issue as I had "light strike" symptoms ocasionally.

This GBB is riddled with problems, pity, it has a nice feel and looks good when new, but after fixing the bogy hop unit (took ages) it worked well for about 200 rounds then the burst fire issue started, fixed that(took ages) then the mags start to leak because of crappy O ring, so in the bin it went. I hope the VFC version is going to be better  because I really like the look & feel of the M&P.

Any update to this? I was also having light hammer strikes today.

To me it sounds like semi-BS. It might be from a WE partner but for WE directly to send out trademarked parts like that, I very much doubt it.

 

Either way good for him.

 

I got mine in the mail coming to me! By the way, price for me was $132 USD, so not the previously stated 180.

 

Also, from what I have gathered these are made by the "infamous" "Ghost Island" "shop" or whatever they are. Still unlcear as to who or what that/they are and/or their relationship with WE...

Sounds like moo-moo milking because everything else I have gotten from KIC Taiwan has been on par with HK prices. They bump up the price from the website abit for foreign customers.

Pulled out the output valve from all my mags. They look perfectly alright.

 

Maybe a combination of running propane and warm weather and increased pressure within the magazine and combination of weakened hammer spring. When troubleshooting the other day, the gun shot normal after about 10 or 12 weak shots and manually cycling the slide. It did it with every new mag (topped off bbs and gas) I put in.

off the top of my head im guessing the valve knocker or knocker disconnect is worn down, and the higher pressure is enough to push the knocker back over the diconnector early before the cycle is complete

Thanks, TnL. I'll look into it when I build up the competence to pull apart the fire control group. Going to do some more troubleshooting with newly lubed o-rings.

I bought the HK3P version of the WE M&P. It immediately had issues alternating between going to full auto or not reseting the hammer. The store (Hero Arms) cautioned me beforehand this was common. I had the store do the upgrade which appears to have resolved all the issues.

 

Markings are like ... crazy shallow, but the overall finish is better than the OEM non-marking M&P.

What the... Your trades on that one is even less visible than on mine... Strange.

Also sucks to hear about the fire issues. Will have to check mine out and fix it...

Well, the iphone quality pics doesn't help. But yeah. That's the current standard for the HK3P trades on the WE M&P. In person, it's not as bad, but they are definitely thin and shallow.

uscm, who makes that threaded outer barrel and thread protector? Looks sweet.

 

Haven't been messing with my M&P much, but using green gas and I haven't had much problems with light hammer strikes. I did find one magazine did it but it was sitting in my rig for a few hours. I still would like to change out the hammer spring.

 

A pic of mine in a HSP INCOG and D3 rig.

It's actually made by WE ... but the BS branding on the package says American Defense Manufacturing (ADM). Basically it's a WE barrel insert which comes with a thread protector. They've done the threaded inserts before as a prepainted orange plastic thing for US sales. And I've seen the threaded part in black too. But never with a thread protector which was why I bought it.

Hi all - new here to Arnies. Anyway, my front sights fell off during a game (kind of my fault, I noticed the securing rod starting to stick out but didn't think much of it). I know some have mentioned that RS front sights are likely to work on it with little/no modication. Has anyone installed RS/aftermarket sights on this? If so, which sights did you install?

Despite the Trades being light and shallow its still a nice better touch then no trades at all. Have been debating whether i should pick a M&P up or wait for a Marui Version
