Hm actually having some cycling issues atm. Think the nozzle is getting caught at times, will have to tinker with it. Right now just slapped stock nozzle in, will see how it games tomorrow!

Not having any cycling issues with mine. It could be the screw that goes through the nozzle to hold the floating valve in place.. Make sure that is loctited and secure. I didn't loctite it at first and it unscrewed slightly and cause jamming. 

 

I haven't gotten round to modding the UAC hammer parts yet either unfortunately!

I had cycling issues with the stock parts last week,; nozzel seems to get stuck stopping the slide returning to full battery and occasional double feeds (think they may be connected). Added some silicone to the BBU hoping that stops it... now to tackle the leaking magazine!

Hmmm I noticed racking it, there are times where it stops and cannot return! Slide catch is not engaged. Dunno what is going on T___T  When i gamed it today, it would not fully return, and Id have to push it and it works! Sometimes no problems though :l

I'm having cycling issues too.  

Cav.. thanks for the updates.. From what your describing.. I have the same thing.  No idea what the solution is yet :(

 

I won't have time to look at it for the next little while, but I'll keep looking at these posts.

 

Cheers

Mine is all stock... when I rack.. all is fine now.

 

However... I still have the same problems of double feeds (Occasionally) and more often it doesn't complete the cycle.  I just need to nudge the slide forward.

Very strange! I didnt have any problems with stock setup

That's very strange all of you.. My complete upgraded M&P is having no issues. Are you sure you've got the BBU low enough into the slide. Are the runners flush?

Not sure, I hammered it down so it's gotta be sitting low. Will need to do some further testing!

You running alum nozzle delta? Cav is.

 

Other than the UAC trigger parts mine has everything you can put in it. It'll have the trigger parts tomorrow should all go to plan!

Strange indeed. Did you actually hammer it down?? You may have actually misshaped the BBU if you actually hammered it? :/

Let's say gently hammered it down, only the rear area as it was more solid :)

Ah I see.. and the guide rails are nice and smooth? Try the BBU without a nozzle installed see if it gets caught still.. If not try manually cycling it over and over for 20 mins or something.. I removed the spring and just cycled the slide to get it nice and smooth and wear the new parts in.

I have the silver Nova slide. It's just as snappy. With the slightly added weight it almost seems to kick more. Really is very nice.

Did you fully tighten the allen screw that holds the faux extractor? I noticed my guns performance is alittle wonky if the extractor cant move freely. I usually go a turn off of full tight. I had this on all of my detonator m&p9 slides

Having an issue with x2 new mags I have for the M&P.

I've had them awhile and tried running them in but still having issues with them. (Also they have more of a MATT finish, than the original supplied batch, my M&P was one of the first in the UK)

Essentially the BB's are getting stuck in the follower on the way up to the feed lip.
Tried using a different brands of bb's etc. But still the same issue with these x2 newer mags.
Any ideas? Tried a general strip clean and lube to no avail

I also had one of them kinda let the BBU misalign in the slide so i have to remove and reinstall then i cycled with the stock recoil spring. I also use a glock upgraded recoil spring now in my m&ps and the cycle fine. Hope that helps and you get it sorted out.
