Those of you who have installed the Apex Tactical DCAEK kit on your M&P automatics...

I just installed it on my M&P 45 tonight. The package had one envelope marked "2 Sear Springs Included" one of which was the tiny spring that goes beneath the sear and the other is a fatter spring that goes... where exactly?

None of the videos showed it.

I've already done the trigger return spring. The dummy pin that they include in the kit to make reassembling the trigger assembly is sheer brilliance.

Now, about that spare spring... whiskey tango foxtrot, over.

After a lot more reading on various other forums, it appears that the fatter sear spring is for a newer version of the sear cage. I have no reason to now, but I will probably order the newer sear cage at some point and enjoy whatever (in)tangible benefits it brings.

Wonder if this is only for the 45s, my kit for the 40 did not have the second spring.

Randy told me that, once the DCAEK kit is installed, there really is no benefit in the larger spring.

They just recently started adding both springs. S&W wouldn't tell them when they switched to the MA spring for all guns, so Randy has to add both.

Yeah it's the MA compliant spring for the newer guns.

"MA compliant"???

"MA compliant"???

Massachusetts. I believe they have rules about minimum trigger pull, so larger (and heavier) springs are required.

Wow! Are you serious? That's wacky!
