7# After Apex DCAEK?

[BHogan]

Hello, first time posting after years or reading. Have a quick question that I hope hasn't been asked a million times already.

I have a gen 1 M&P 9c that I just installed a full Apex duty/carry action kit in. Install was easy and it's all much smoother, but I'm finding my pull isn't at all what i was expecting. I'm about 5# to the wall, and 7# to break vs the 5 I'd expected. This is with the Apex return spring and I understand that the original spring may give me about 2 more pounds, but I'm wondering if this is something anyone else has ever run into, and maybe something else is going on that I should address? Tons of searching, but not finding much. I ran a couple hundred rounds through it today with no improvement. Any ideas? Thanks in advance!

I believe the original spring will reduce the trigger pull by about 2. Contact Apex customer service and ask them to be sure.

As mentioned above, reinstall the factory trigger return spring. The Apex spring indeed results in a heavier pull. I have installed the Duty/Carry kit on several and have always used the factory return spring and all have roughly 5.5 lb pulls now.

Thanks guys...I'd read that the factory spring would give me back about two pounds, but thought it should take me to 3-3.5 so was trying to figure out why I was two pounds high...Msjdgman, your post is helpful, sounds like you were/would be at around 7 pounds with the Apex spring too. I'll just switch them out and not worry about it!��

When I had the kit installed i bought the one that came with the new plunger kit and the new trigger and new sear. I had it all swapped out and kept the stock s&w springs and I now have a 4.5 pound trigger pull with no malfunctions. Mine was close to 8 before the entire kit install.

Well, I swapped the spring out for the factory original tonight and i definitely softened the takeup, right at 3# now, but it still fights the break and even with that spring I'm up around 6.5#s or more. It's really variable too, more than any other gun i have. I'm wondering if it's the wrong sear or something I've read so many great things about the kit, just know this isn't it. I'll keep the thread updated after I talk to them and figure it out for posterity's sake.

Did you just install the sear kit? If you want it smoother with less take up and hardly any reset then you gotta get the trigger kit and plunger kit.

Yeah, it was the full kit...sear, plunger, trigger, and springs. No matter what I do I'm still at 5.5-6.5#s, really disappointing. I talked with Apex and they were really helpful, but basically said unfortunately some of the M&Ps just have heavy breaks. I guess I got a "bad one!"

I'd send it back if possible.

I would do close examination of the plunger and its machined hole it resides in.

I probably said that kind of unclearly...I believe the kit itself is fine, but my actual M&P has a heavier than usual break which they said sometimes doss happen. I did some really light, like 2000 grit polishing on the mating surfaces of the striker and sear and it helped a bit, I'm breaking right at 5# now with the the factory trigger spring which is about where I want it. I'm sure I could make it better with a little more polishing but I don't want to screw anything up!

Have to say to wrap this up, the team at Apex is first rate, really helpful people. I definitely have no problem with with the kit itself and will do it again if I get another

Yes! I put in the same kit you did and the trigger was as bad as the factory one! I removed ALL the Apex springs (kept the parts in) and replaced ALL the factory springs.
The trigger was awesome and broke at 5.5 lbs average. Smooth as silk.

Be SAFE andShoot Often!

Coming back around to this after a few hundred more rounds down range in case anyone searches it later. Long story short, my pull improved dramatically with use after installing the kit. I'm now at a very consistent 4.5# with the factory trigger return spring and apex parts. So that's nearly a 2# improvement from baseline just from more rounds fired. Note this was in a gun that was fairly new but had maybe 300-500 rounds through it. So I guess lesson is if you install the kit and aren't where you thought you'd be, keep shooting. In fact, if it continues to drop I may go back the apex spring, I really don't want it much below where it is TBH.

Mine was the same way, close to 7 pounds. Doug at Apex told me to put the factory return spring back in and it should drop 2 pounds. It did, and since then has got smoother.
