SD9/40(VE) owners with gritty trigger apex or not...

[raymo2u]

i have had the gritty trigger issue as most of you have since the purchase of my sd9ve. i polished all moving parts/faces/touching spots and i did help but pulling slowly on the trigger when racked it was still hard to stage perfect most times. thus i added apex spring kit, which lightened the pull greatly the gritty staging problem was still present. i added the m&p aek whick was nice and added to the overall feel of the spring kit it did nothing for the grittyness....

soooo after looking over and over and the internals i thought it was the trigger bar grinding the slide...polished that...helped nothing

finally i took the striker out and noticed when compressing it in my fingers it had the same grittyness the trigger had. i took some graphite lube and a q-tip and rubbed it all over the striker and spring and the plastic tubes and casings. i checked the compression again and it was smooth as silk. slapped the pistol together, racked it, and i finally have solved the grittyness in my trigger while racked. lube the striker and parts and see if that helps you like me.
it now is as smooth as my sig p226 navy is stock

I don't think you are supposed to lube the striker.The lube will get dirty and bind up the striker.I would try to buff and shine the striker spring as best I could to remove some friction and leave it dry.

 

[raymo2u]

graphite lube is a dry lube...if it binds i will gladly clean and reapply. it doesnt attract dirt or oil or grime and can withstand immense heat depending on the brand you use. how dirty does your striker get when dry anyway? so being dry but having less friction i think would create less wear and less material build up.

The apex kit got rid of my gritty trigger.

You added the M&P AEK to what gun ?

Not sure if there is any aluminum in the trigger bar or other small parts but you should be aware, if your not already, that aluminum and graphite dont play well together.


ETA Its possible taht the M&P triger in the SD may be the source of your gritty trigger since Apex stated that the SD trigger required a notch that the M&P trigger did not. Just something to think about.

the grittyness was the same before the polymer aek was installed. ive had zero issues with it installed on my sd and ive mentioned this in the other thread. it seems to be my striker assembly was catchy/rough when compressing, hence why i hypothesized to use lube, but a dry lubricant.
ive only added the graphite to the striker, spring, collars, and inside the white tubes. it was wiped on with a q-tip so i dont think it shall spread elsewhere. if you know the parts youll understand its pretty enclosed and the material added is barely enough to get your fingers dirty while installing them.

I have tried to find any differences between the two triggers and could not. Does anyone have any info or photos to show these differences?

Just curious.

 

[raymo2u]

apex has stated that people should not use the m&p triggers becuase 2 of 4 sd test pistols had fatal failures with them installed the other two perform flawless. i couldnt find any difference either but stopped advertising use of the aek in the sd becuase of the apex statment. apex will be releasing the sd aek soon and i will compare them and see if there is any differences. as i mention before in MY sd9ve the m&p poly aek improved the overall feel of the trigger but changed nothing of the grittyness i observed before installing it.
i have done some research on the whole lube/not lube striker topic and it seems it is just a preference. those who just quick clean and lube i advise against it, those like me who clean every aspect of their pistol every use and relube i advise it.

If the M&P AEK trigger is like the original M&P trigger then what are the differences between that one and the original SD trigger regarding the geometry and where the trigger bar connects.

I know the obvious thing is the absence of the squishy part.

Thanks,

the comparison was between the m&p poly aek and the sd trigger...overlooking the obvious cosmetic and struture where your finger pulls, but more the question as to what and why it would/should not work in it. it slips right in place and has the same dimensions in the places needed for it to work in my gun, thus i dont see how it wouldnt work. ive told so many times it wont and theyre different but mine dropped right in.
i do not have a m&p stock trigger to compare to the sd trigger. they were very similar to what i remember.

 

[brchambersjr]

I just find it odd that it is not supposed to be for the SD and you have shown that it does indeed work without some "notch" or any fitting. I am just curious to see the differences between the triggers and how they look when attached to the trigger bars.

Is there a difference between the poly and the aluminum aek? All of the pics online seem to show them to be very similar and I would think that they would have to be to fit the same style pistol.

in the other thread sd mag extensions i called apex out on that, how i dont see why they dont sell the aek's for the sd just using the m&p. i have, 4 of my friends are and there is a video on youtube that i posted in the other thread showing the instal and function of the poly aek in the sd9VE. none of us have had issues but i guess apex did during testing and deciding it wasnt relible enough. when they release tge sd9ve aek i will be comparing the m&p aek and the sd aek for final reporting, until then im very happy with my solid trigger.
the aluminum trigger is the same just aluminum and more exspensive for the same thing
i dont see where the whole notch cutting thing comes from or where would it need be done? it sits the same way back feels better, like its not flexxing when being pulled or the mushy feeling from the saftey the sd trigger had. all in all with all the mods ive done: the aek, the spring kit, the polishing, slide on grip, stock m&p rear sight, undercut trigger guard it is just a mind blowingly great pistol for the money and i couldnt be happier now...well maybe a threaded barrel and a melted rds would be nice too

Yeah, I saw the video and I'm digging that trigger. It seems to work just fine. Looks good. I too am very happy with my SD9VE.

Thanks for your feedback.

FYI the aluminum M&P AEK trigger does fit the SD9VE with no issues.

 

[raymo2u]

nice, ill stick with the poly AEK i have now but someday ill get that aluminum aek...the sd AET was just released today btw

 

[brchambersjr]

Yeah I saw that but I really liked the aluminum. I guess it's the slight similarity to the 1911 trigger that I like.

 

[raymo2u]

yea i tried playing with the trigger return spring yesterday using the apex spring and streching it slightly for even lighter pull but i streched too far and now it wont let it reset the trigger. im back to stock spring but its actually faster with the return and the pull seems just a tad heavier and with that aek its really a dream since all the other things are unchanged. i wanted the aluminum aek for the solid feel my sig gives me, since that would be closer in comparison-it will never be a 1911 unless we get a new sear upgrade too

 

[brchambersjr]

Yeah, not the weight but the flat aluminum feel. I guess the pad of my trigger finger finds it familiar. It will never be as light as a 1911.
